Hi Siwai

This site does not deal with VAT refunds this is UK tax forum and you would have been advised how your refund would be processed, either through the shop of through refund company.

Its whoever you posted the form to and its the retailer that you have to chase up see link here from Customs leaflet

10.How do I obtain my refund?

After your VAT refund form has been certified by Customs you can either:

• post the form back to the retailer to arrange payment of your refund;
• post the form back to a commercial refund company to arrange payment of your refund;
• hand your form to a refund booth to arrange immediate payment.

Whichever method is used should have been agreed between yourself and the retailer when you bought the goods.

Your refund may be reduced by an administration charge. This charge should be clearly shown on your refund form.

If you do not receive your refund within a reasonable time you should write to the retailer - not to Customs and Excise

Thanks

Sam
