Bad service or incompetence

On 25th Oct 15 we called multichoice call centre and spoke to Violet to disconnect/suspend our dstv service as we were away (8 mins 26 secs). We also requested a change of our payment date from the 25th of the month to the 02nd, to which Violet told us was done. On the 31st Oct 15 we requested the amount we were supposed to pay and were told R405.00, paid at dstv centre Maponya mall. On the 30th Nov 15 our service was suspended for non payment, we contacted the call centre on the same day and spoke to Tshegofatso, (32 mins 47 secs), who informed me that the change of payment date was not effected. She proceeded to attempted to change the date of payment again and couldn't'. She then told me she was making notes of the conversation and would escalate my complaint to her supervisor and I will be contacted within five days. She provided me with a ref no and said she would request a recording of my conversation with Violet to verify what I said. We were not contacted within 5 days as promised and on the 8th Dec 15 I called the call centre again and spoke to Mpumelelo and the supervisor (39 mins 54 secs) and was promised a response. Our situation has not been sorted still.
