Street Style Store — Unable to use credit note

Address:	Varanasi, Uttar Pradesh, 221005

I ordered a pair of shoes in january, order number 1340380, which was a wrong order and it took two months to exchange it. I was given a credit note for it on march 2nd, and i have been trying to use it ever since. I have no idea what kind of joke these people thing it is, but i would appreciate it if someone helps me get my money back or help me use the credit note. The only thing that my account and email reads is "your order with the reference leqyfqrjs - credit slip created"
Complaining again and again is exhausting and agitating. I had the worst plausible experience ever. Hope you people work on it, and help me out.in fact the store should pay fine to me for the mental exhaustion that i have been going through. It's not just indecent but also violates my rights.
Hope somebody gets on to it asap.
