MTN Northgate - The one outside entrance 1 - Unprofessional services

I came in on Wednesday 24th July 2019 and spoke to Mduduzi Nkwasi. He told me MTN will send me an email pertaining to the query I had in the next 48 hours. On Friday 26th July 2019 I came in and spoke to Tracy she informed me Mr Mduduzi was not there she tried to assist but said he is the only one that can help me with the query as he logged it. She took down my details and said she will ask him to call me. Uptil now I'm still waiting for him to call me. I then went back into the store that Friday afternoon at 17:00 and spoke to Mr Matsobane who is the manager he said he will deal with the problem personally and come back to me by latest Tuesday morning. This morning I called him just after 9am he responded with an SMS saying he is in a meeting he will come back to me after his meeting. I walked into the store at 10:30 this morning only to be told by his staff he left for Clearwater Mall to collect stock. I would like to know how long would it have taken him to call me and given me the status of my request. I find this store very unprofessional from the staff to the manager. I definitely will not be visiting this store again. I'm am also going to the ombudsman of cellular networks after this because it seems as though no one can help me with my request. I have been a customer of MTN for over 13 years and the services I'm getting from this store is appalling.
