BharatPe — Return of Bharat Swipe Machine

I have a swipe machine from Bharat Pe since 3 months. I have been following up with your customer care since 3 month return of the machine. I have also asked for a pick up of the swipe machine since almost 12 weeks and I was told that the machine will be picked up in 3-4 days and my security deposit will be refunded in 7 working days.
