Shocking service

During November 2017 I was contacted by a CellC agent and told that I could update my data contract. I was not keen to update the contract, however she then stated that they had a special offer and that I could obtain 2Gb of data for R99 per month. I then accepted the contract. The agent informed me that I would receive my sim card the following week at my work address. I stated that I was going on leave that week and requested that it be sent the 2nd week of December. As expected, knowing the reliability of CellC, the sim card never arrived. I have since requested on numerous occasions that it be sent to me with no success. Last week I emailed the customer service department and received and email stating that I must contact 084145. So I phoned this morning, only to be told that I need to contact another (I think escalations) department. This was the final straw as I am being charged for a contract that I am not able to use, and I have now requested that this contract be cancelled.
