Poor customer service from a factory phone problem

I had to choose one star because I do not ont to. I had no choice. I upgrade to a p40 lite and had to wait for a week to set it up because Im a samsung user. When I got to the store the store was closed I had to go to another store to set it up. The phone gave me problems and took the phone back the next week and hand it in an with lots of calls I still not have a phone but are paying my phone bill. Im not happy after 7 weeks i still dont have answers from branch to reagenal manager still no answers. Mtn SA cape gate asked me until today 13 July for a new phone and no answer from regeanal mamager branch saifs the cannot do anything... I want a phone today.... Im a nurse and dont get work in because i dont have a phone They still said phone is in transit... for 5 weeks now the phone is in transit
