Cell C refuses to be of service, but wants money

I have been struggling for more than 3 weeks to get my fibre installed after I have signed a contract with Cell C. The consultant stopped answering my messages and/or calls. I tried to escalate the matter to no avail as the team leaders seems to be too busy. I am losing money as I cannot work. You guys are too big to care about my livelihood or how I am going to care for my family. I will never recommend you again and I want my contract canceled immediately!
