INCORRECT CONTRACT

On 12/04/2016 I contacted Cell C and I spoke to Temba Zabala. I wanted internet contract for 5 gig day time and 15 gigs after hours at R99.00pm. Temba helped me and he set up the contract. On 13/04/2016 I received the router on 14/04/2016. I received a call from Temba at about 8.15am telling me that he made a mistake and he set up an incorrect contract for 1 gig only but the matter will be fixed the same day. Nothing happened. I phoned again on 15/04/2016 and I was told by Temba that definitely it will be resolved on Friday 15/04/2016. Nothing happened. I phoned today 18/04/2016 and another consultant informed me that a supervisor will phone me before close of business - nothing happened. At 4.40 I phoned again and I was advised that an e-mail will be send to the Supervisor to contact me - nothing happened. I am now very furious
