Jovial Mart — I have to return my item

Sir i had bought the combo packs of 3 jeans, but the size of the pants is small. Sir i want to exchange the pants. Your product quality is good. But sometimes it is not up to the mark of costomer satisfaction. My product id is-14406 and invoice no is-HAL[protected].
Sir kindly look into the matter.
I will be very gretful to you
Thanking you sir
