How to report a double charge in English (B1): cost, charge, pay for and a clear refund request

Cost, charge and pay for: who does what

Each verb sees the same money from a different side, so each one needs a different subject.

• “The new drill cost £240.” The item is the subject; the past form is cost, never “costed”.
• “The supplier charged the studio £240 for the drill.” The seller charges the buyer.
• “Owen paid for the drill with the studio card.” The buyer pays for the item. With an amount or a bill, drop for: “We paid £240”, “We paid the invoice”.
• How you paid: “by credit card”, “by bank transfer”, “in cash”.

Worth, afford and owe: say why it matters

Say what the error means for you.

• “The drill is worth about £200 now, although it cost more.” Worth is value now, not the price paid.
• “The studio can’t afford to pay the same invoice twice.” Afford takes a noun or to + verb, never -ing.
• Owe is money you still have to pay: “We still owe £90 on the equipment loan.”
• You borrow from someone and lend to someone: “Can I borrow £20?” but “Can you lend me £20?”

Past simple for the purchase, present perfect for the problem

Past simple: a finished event at a finished time, stated or clear. Present perfect: a past action that matters now, with no finished time. A complaint usually needs both.

• “We ordered one drill yesterday.” A finished time.
• “You’ve charged us twice.” The money is still missing.
• “The supplier has returned the duplicate payment.” A result now. Add a time and the form changes: “The supplier returned the payment at 3:15 yesterday.”
• In a follow-up call: “Has the refund arrived yet?” “It hasn’t arrived yet.” “I’ve already emailed the receipt.”
• The passive, when the company did it: “We were charged twice for one drill, so the second payment needs to be returned.”

Listen: one purchase, two charges

Two colleagues spot an error on their card statement. Notice the amounts: the drill cost £240, so the extra charge is £240, not £480.

The call: facts, request, deadline, confirmation

Keep each step short. “Could you…?” sounds polite; a fixed day and a written confirmation sound firm: “I understand mistakes happen, but we can’t wait until next month.”

• Open: “I’m calling about an order we placed yesterday, reference 4471.”
• Facts: “We paid £240 for one drill, but our statement shows two payments of £240.”
• One action: “Could you refund the second payment, please?” Or, in payment language: “Could you reverse the duplicate charge?”
• Deadline and confirmation: “When will the money be back on the card?” “Could you confirm that by email, with a reference number?”
• Summary: “So, just to confirm: you’ll refund £240 today and email me a reference.”

Questions to discuss

Answer aloud: a past detail, then a present result.

• “Have you ever been charged twice? What did you do?”
• “Is a payment problem easier to sort out by phone or by email? Why?”
• “What have you bought recently that was worth the money?”

Common mistakes

Most come from translating the verb instead of asking who does what:

• “I paid the drill.” Say “I paid for the drill.”
• “The drill charged £240.” Say “The drill cost £240.” or “They charged us £240.”
• “I have ordered it yesterday.” A finished time needs the past simple: “I ordered it yesterday.”
• “We can’t afford paying twice.” Say “We can’t afford to pay twice.”

A 10-minute daily practice routine

Say everything aloud first.

• 2 minutes: play the conversation and note what each amount refers to.
• 3 minutes: three true sentences about a recent purchase with cost, paid for and charged.
• 3 minutes: role-play the call, from the reference number to the summary.
• 2 minutes: write the summary you would say before hanging up.

What comes next

Put the same facts in a factual complaint email with evidence. If a cash machine returned your card but no cash, practise reporting that. Or explain a small study without overstating it.
