Question for J Mann & Co Pvt Ltd

Good morning

I purchased 63mm class 12 poly pipes x 2 rolls of 100m each (that is 200m) under timsite ent. p/l, bindura from your company on the 3rd of October 2018. Now I need to make a return for bigger size of the same quantity. The challenge is that I misplaced the invoice/receipt.

How best can you assist me?
