Review of Nokia Cellphone Warehouse

Purchased a Nokia asha, stopped working on watsupp and Internet 2 days later. Took it to them and was told sorry, but the phone would have to be sent for repairs, after threatening to see managers the counter ladies did settings on the phone and it worked again for about 2 hours. Phoned and asked if I could be reimbursed or phone swapped for another and was told no, the phone had to go for repairs and it would take 2 to 3 weeks. A brand new phone that lasts 2 days? Sorry Nokia and cellphone warehouse, you dropped the ball on this one
