Still no service from cell c

AS per previous complaint did upgrade on my phone @ Sandton city, wasn't communicated 2 that upgrade would not be effective. Went to Norwood as phone wouldnt let me make calls. Was told that upgrade would only be effective from 1 Jan & only choice I had 2 make calls was 2 increase my credit limit...********* from cell c. Sent a complaint via cell c website. Waited 2 weeks but no response from Cell C. In mean time had 2 load extra data onto contract. Complained on hellopeter & was given call from Cell C who basically told me that that they'd spoken 2 branches & that I was confused. Upgrade would only kick in on15th. Then told I must contact the branches if I want 2 take further. I asked if branches could contact me and was told by head office that they would get Sandton and Norwood branches 2 contact me. Still waiting for them to call me. In mean time I go back to Norwood cos again today phone not working and they tell me that no actually there is no 2 gigs of data in contract & actually upgrade is effective from 1 Jan. So basically everyone you speak to gives u a different story. Cell C head office said they'd refund half. BTW cant use phone today and told credit limit now R50!!!
