Paytm Mobile Solutions — all 3 products returned but no refund

This is the worst experience of me with paytm mall. I ordered 3 trackpants from paytm mall & the quality was totally different so i returned all 3 products. They have taken there products back but paytm is not giving refund & when i call customer care always & anytime its busy (They do not pick call). My products order number are as follows: 1) [protected]. 2) [protected]. 3) [protected]. I request all o[censored] never order from paytm mall. I am sharing a screenshot (This is what paytm says from last 7-8 days buy not refunding me my money back). Please help.
