Paytm — receiving damaged chimney and not picking it back from paytm

Sir,
Paytm executives are so much irresponsible that they are not able to arrange a pickup for my damaged product, and now i have to even pay the emi of this damaged product. Everytime i call in paytm the executives are just delaying the pickup and are asking for 48 hours. But i t has already been 15 days but they are not taking any action. The onlyu work they are doing is harrasing me by making fake promises. The resolution is to make the emi cancel from bajaj finserv and making the pick up as early as possible.
