Paytm — Jbl flip 3 bluetooth speaker

I have ordered jbl flip 3 speakers from paytm more then a month ago. The product was not delivered to me and it was showing on app that it is delivered. When i asked to provide refund (8143/-) they took almost 25 days to provide the refund. The payment done by me through my cc and it was on emi. After providing refund they have charged 6850/- as a pre-closure charges. I have provided them all the references and evidence showing that the amount is debited for the same order still they are not providing refund and saying that it is charged by your bank and they need next credit card statement. When i asked to my bank they said it is charged by merchant only. I have already provided screen shot of all the debits and credits of cc account for the current month still they are not providing any solution and saying we need statement in pdf format instead of screen shot. It is already more then a month for this issue and i am totally fed up with the service of paytm. I need my complete refund asap.
