Quikr Doorstep — They failed to make me payment for item sold.. Now they say the order is cancelled

Address:

Ranga Reddy, Andhra Pradesh, 500088

Item that I sold was picked up on 13th Arpil. I got confirmation that it is delivered to buyer and I can expect payment of Rs.4000 within two days.. But now the ad shows the status as order cancelled and no answers on when I will get my money. The executive admits a possiblity of technical glitch but did not give any ticket number for resolving.
I would appreciate if it gets resolved soon..
