Extremly bad service from MTN

At the 28/10/2020 I took a data contract with MTN at Kwa Dukuza /Stanger Mall Invoice no :INV***2 The problem started at the 26/11/2020 I had no more data, went to the Kwa Dukuza Mall store to query my usage , the team did not know the cause and did a fault registration with the data team. Friday 27/11/2020 at the store I was shown a printout showing a usage of 30.88GB, my contract should give 50 GB anytime data 20 GB are missing and a fault was logged Saturday28/11/2020 at the store , no reply from the data team , fault was escalted by the store manager reference no *** Monday 30/11/2020 at the store still no reply from the data team, this nonreacting to a fault made me very upset and I requested to cancel my contract, the store team connected me with a cancellation call centre team , spoke to Sebisio and requested to cancel my contract and got told by Sebisio that I had to pay a additional R707 to cancel the contract ???? I did not receive my due data MTN and I pay for no service ? Declined to cancel at this time as the store team motivated me to get the data team to waive the penalty of R707. The store manager again escalated a query to the data team Friday 4/12/2020 again at the store and still no news re missing data This was for me very poorly work ethic from the data team. I understand that Black Friday caused a lot of work , but if MTN can not manage the work, they have to employ more staff. Wrote a to complaints@ mtn.com about my very bad experience, no reply as yet, how very bad management. Today is Wednesday 9/12/2020 again at the shop awaiting any news, Requested to cancel the contract, spoke to Nonhlanhla from customer service and explained the situation of missing data , still no explanation and to waive the cancellation penalty of R 707, she logged a query Ref no *** and transfered me to a cancellation agent and I waited foe about 45 minutes and than stopped the call . I the meantime I received a sms 14:17h : Dear Customer , Your query *** has been closed Nothing has been resolved, but to send such a message shows a disregard of understanding whats going on , and with my fees I pay people like this. After todays action I went to write on Hello peter with my grievances. The service I received from different customer care agent were so poorly , the non interest, the non problem solving ability, unable to speak to a senior care or in charge consultant is bad management , unprofessional and ashaming service from MTN. the TRAINER OF CUSTOMER CARE AGENT SHOULD DO TRAINING THEMSELF. The disregard of the data team in answering questions seems to be non existing the repeated & escalated query was ***. As a long time customer of the MTN store at Kwa Dukuza Mall , I am impressed with the patient of the store manager Linda to deal with my ongoing unhappiness This has now taken 2 weeks and is not resolved, may be hello pter is the answer
