If Maplin cancelled your order after taking payment, you need to get in touch with them right away to get your money back. To start the refund process, go to Maplin's Help Centre and call customer service.
Maplin's policy says that if you cancel an order before it ships, the money is held by your card company and not taken by Maplin right away. But it could take up to 10 business days for your bank or card company to put the money back in your account. Maplin has no power over this time frame because it is set by the card issuer.
If you don't get the refund within the time limit, call Maplin's customer service again to find out what's going on with your return. Please provide any relevant proof, like transaction receipts or bank statements, to help solve the problem quickly.
