Requesting several times for pickup amazon is not picking up my product.. And the last return date is 1st feb... I m totally hopeless as i am not getting my refund.
I am not able to self return the product as my working hr is from 7am to 7pm.. Felling totally hopeless.. Don't know what to do.. I had mentioned that i will not able to self return it due my office hour... I am talking about my ray ban sunglasses... First day when they delivered the product i got an empty box... Then i mentioned them the issue after one or two day i got the same delivery on which the sunglass is there... Pls resolve this issue as last return date is on 1st feb
