Ticket #[protected]: Merchant cancellation
Oorder number [protected]

I have placed a order on the deal price. And its was cancelled next day. When i ask the reason to patym care its was told to me first that no stock available.Later i replied that i am ready to wait for stock, then again while speaking it was told that due to wrong pricing we are unable to deliver the order.
So my concern as a buyer is, i have chosen good deal price and booked a order.
If the order is cancelled due to wrong pricing, is that mistake from me? And how do i known its wrong pricing or offer price.
Finally me have missed other deals, offers, time ending up getting fooled and cheated by PATYM.

So experts pls help me get this resolved .
