Bad Service offering from Cell C

Hi. Jordan C wrote almost exactly the experiences I have had with a similar 100 Gb data contract with a LTE-A sim, which is described there. I also have been off of the internet with the same description since the 18th of April. The persons I have spoken to at Cell C have said that Technical will call and sort out the problem. When I call Cell C technical I NEVER get through to technical and end up speaking to Customer Care who cannot help with this type of complaint. However Technical NEVER calls and therefore I have no Internet coverage. I have been using an alternative sim with data but my 100Gb this month is untouched. In Feb the first month of the contract Cell C could not get the sim connected and I lost 28Gb, and in March I only got connected about 12Th of the month and I was able to use a couple of Gb. Then the streaming speed was so slow at times it was useless even trying to stream. After dozens of complaints, just before end of March, the speed slowly picked up. I managed to use about 8Gb. Came 18th April I could no longer use the sim or the data on the sim. I am now at the stage that I will cancel this contract and NOT renew any of the five contracts which I have with Cell C. PLEASE DO SOMETHING VERY SOON.
