WORST CONTRACT SERVICE EVER!!!

I would just like to encourage everyone to NEVER support or make use of this service provider, I purchased a phone via customer care the first thing I told the agent was that I wanted to make my prepaid number my main contact number long story short they ended up deleting my number, after numerous back and forth with agents as well as going to cell c store they finally managed to assist me. After fixing my number the brand new phone went blank and I took it to cell c it has been two months with no feedback every month they take my money they didn't even offer me a loan phone I have to borrow a phone I missing out on everything. If anyone can advise me what I can do to have this issue resolved I contacted ICASA with no success, I have left numerous complaints on the Cell C email I even requested head office's number and no one that works there can assist me I have various numbers I received from consultants I can even provide their names I am still waiting for the managers who are constantly busy to give me a call back. I have had enough with this pathetic service provider they deduct their money every month without fail but I am not benefitting even if I can get a good lawyer's number I am ready to go that route
