I had purchased a mobile of moto g5 plus (32gb, fine gold) on 9th aug 2017 and product was delivered on 11th aug 2017, but due to some reset problem on product we were raised a request to replace the product, and subsequently amazon pickup boy was picked the product with giving a track no as[protected] in return, my mobile imie no :[protected].
We have been talking with customer executives a lot of times but didn't get any positive support from their end, it is very ridiculous to inform that we already lost our patience level.
It is very bad service from amazon, every time we called and explain the detail scenario about the problem to each and every customer executive, and every time they casually handle the problem and uses the worst word like "we have updated in the system", "refund has been initiated in the system"like that many more, but are they not even update our problem in their system, and in fact amazon system also having a lot of issue, so please look in to this matter and replace my product as soon as possible.
