I bought something at galeria lafayatte on 10nov, and i got bzck the tsx refund in cash euro41 straight away on the same day. I had no idea that i still need to drop “tax refund form” to the custom. Now i lost the form, probably i throwed it away already as i thought the procedure has completed after i got back in cash. Tomorrow i am leaving to zuruch from germany. What should i do now since i lost the tax refund form?
