Faulty handset

To Whom it may concern <br> <br> I took up a contract in Dec 2014 from the Fordsburg branch . October 2015 the phone gave me problems ( the screens goes blank ) . I called the Fordsburg branch and was asked to check the phone in. 19 Days later when I called to follow up I was told that the phone cannot be fixed and I need to come collect a new phone. I fetched a new phone and 3 months later , the phone is giving me the same problem. The manager of Fordsburg branch as well as Herman the consultant is totally useless . I had to check the phone in again . My question is how can 2 phones give me the same problem . I refuse to take the phone back . I want this contract cancelled if not then I need a new contract from another branch. <br> It this is not resolved urgently I am taking it further with the Ombudsman <br> <br> Regards<br> Nazeera <br> ***
