The seller received his product three days ago and they still haven't refunded me back now they are saying they will refund me in 5 working days bank policy first they said 7 bussiness days than they lied to me saying as soon as the sellers gets his product back than after 3 days they will refund me and now the seller got back his product they have extended another 5 days and after that they will again extend another 5 days this will go on i have wasted whole october in returning and picking and they wants me to waste whole november for refunding they are just building up lies please i[censored] can help me to get my hard earned money back..
