BAD SERVICE

On the 8th September i upgraded my phone tectonically they send it to me on the 10th September and then i went to cut my sim card because it did not fit in the phone and then the next morning while someone phoned me i heard for the first time that the speaker at the Back did not work correctly and the front one aswell it scratched the whole time struggling to talk to someone on the phone i mean really it is still brand new... anyway i went to 3different stores 1in Free state and 2 in Pretoria no one could assist me or replace my phone then this morning on the 14th of September i phone The Call Centre again and now they said that they will arrange with me so that a courier will come pick up the phone after they receive it they will send me another but i already cut the sim card so cant put it back in an old phone because it is to small now and all that they can say is they cant do any ting about it I HAVE TO WAIT -7 DAYS i can NOT go without a phone till they bring me a new one it is probably a factory fault but its not my problem it is the worst service and cant believe they do not care anything for they clients wont go an extra mile to help them.. now i am gona lose clients!!!!
