INEFFICIENT STAFF IN CALL CENTRE

I have 5 contracts with Cell C & do all my business/upgrades at the Greenstone Branch (staff r AMAZING!) but in Jan I was HOUNDED by Robin Summer from call centres his phone number ***. He HARASSED me endlessly daily wanting to upgrade my account. He said that my Giga 20 Postpaid contract no longer existed & I had to change to a Top Up contract. Eventually, after he phoned me non-stop I agreed with the understanding that my SMS bundle would still be loaded monthly onto the account. He assured me the account would remain the same (it would even be a bit cheaper). On 26Jan I received confirmation of contract reflecting bundle. BUT when I tried to send SMS's-NOTHING. Contacted Cell C on 2Feb was told they would load them. Contacted Cell C on the 4Feb & was told on this contract you can't load a bundle & have to buy bundle monthly using my sim card. I have to take SIM card out of ****le, put in my phone, buy sms bundle then put back in ****le. PROBLEM-My phone micro SD, ****le Large Sim. *** (at same time asked them to streamline my billing). 8-3-16 phoned they said on this ref. only billing query. Will request call tapes ***. Want my old contract!!!
