Purchased an entertainment unit (Id[protected] on 23rd june. Firstly the delivery was delayed due to product not available. On 13th july raised a return/cancellation request. Also spoke to their cs head sandesh koli who agreed to return the the product. Have mails from him as well.
Even after that we got delivery updates and repeatedly told them that order is already been cancelled.
Yet the product landed at our door step on july 16th which we did not accept. The delivery guy also called up his superiors and took the product with him.
After this nobody picks the calls, sandeep koli does not respond, call centre is useless, no reply on mail and we are still struggling to get the refund
