Cell C is such a joke

Cell C wants me to pay for something I am not supposed to, last night I called to put a month's notice for my contract to be cancelled on the 6th of this month. i was advised by the consultant who was assisting me that for May I will get pro rata of the benefit and will pay for pro rata of my monthly payment. So what happened is that at the begining of this month they gave the full benefits. I called them to query this and was advised that i will only pay for what I use. And a consultant was supposed to be in touch with me to confirm that and I still haven't received a call from them. fast forward to today, I called them to follow up on the consultant that was supposed to call me and i am advised that I will pay for the full month as I was given benefits for the full month. First of all I did not even use those full benefits because I knew I was not entitled to them as my contract was due to end. Secondly this is not the first time I am cancelling a contract with Cell C and its the first time I am hearing that I will pay full benefits even though I had the contract for 6 days. to top it all off, the lady who was assisting me on the phone was rude and could not even explain what is going on. i am sorry if this is how cell c does business I am not happy to be dealing with them in future.
