Tata Communications — return pickup of my product!

Address: Nellore, Andhra Pradesh, 524003

I received a faulty product and I immediately reached out to customer care at Tata cliq on 14/6/19. My pickup was approved on 15/6/19. But my product is yet to be picked up. It is 21/6/19 today. I reached out to the courier partner assigned for my pickup, Delhivery and they said that the their branch in our town was closed down recently due to operational difficulties. So I have been reaching out to Tata cliq representatives regarding the same since 4 days and they just keep giving me the run-around without providing a proper resolution. I have been requesting them to just change my pickup partner since 3 days but to no avail. It's been 7 days. Please help.
