Return policy

I bought gym wear at the workshop branch and u fortunately they didn’t fit me how I wanted which sucks because I walked into the store 10 minutes before closing and by the time I picked the item up it was almost closing time. I no longer have the receipt so I called the call centre and they said tgat can’t help me even though I made the purchase with my bank card and you can see the purchase in my bank statement, the lady from the call centre then told me She is transferring me to the store line and the call just ended . Can I please have assistance this is very unfair and unjust , especially because I have proof of payment. The item was pricey and the size should’ve fitted me fine if the cut wasn’t so small .
