Pathetic network provider

So i have 3 contracts with cell c. A total of R1429 a month. 2 cellphones and a wifi contract. I live on a farm and i been telling them the signal is ****** pathetic but still no technician came out to assess the network etc. I did not even get any feedback from the call centre. So june is my last month for wifi contract. I asked for it to be stopped. The call centre keeps calling me to take a data sim contract i refused. So cell c tell your ****ed up call centre people do not call me and also i dont wish to take anymore contracts with you stuoid useless network service provider. I mean yourll cant sort the issue in my area but want my business. **** yourll. My other 2 contracts come to an end in july 2020.il never renew again with you useless cell c.
