Bad Service

I was contacted to upgrade my contract. I upgraded to a Sony Experia M2 Aqua. The cellphone was delivered to my work address on the 27/2/15. I did the sim swop on the 1/3/15 at CellC The Glen Shopping centre.<br> On the 4/3/15 the screen of the new cellphone was scrambling with 4 thick lines vertically across the phone. <br> On the 5/3/15 I spoke to Nontobelo and she said the phone would be collected at my home address at my request because I was on leave for a few days. The phone was never collected. On the 11/3/15 I spoke to Lucy and she said the phone will be collected the same day. No one came to collect the phone. <br> On the 12/3/15 I spoke to Sharon and she said the phone will be collected today and this went on where I called<br> CellC almost everyday up to the 26/3/15 when the phone was collected. Iam frustrated because I have been without a cellphone for almost a month and Iam fed up. The phone is with them now and they have to assess the phone for 7 days. I phoned today to ask what was happening and they told me the is collected but needs to be assessed and then only will they let me know. They were not prepared to speed up the process or help me in any way. Do not use CC
