HOW MUCH DO MTN REALLY CARE ABOUT CUSTOMERS

I have had a cell contract with MTN for probably last 20 years. Currently have two cells on the contract. one of the phones is due for upgrade. I contacted RETENTIONS dept and discussed upgrading. the agent emailed me an offer after the discussion. I emailed back asking if ,as month end was approaching, could hold offer to see if new month had a less expensive alternative. The new month had SAME offers so I emailed accepting offer. Agent said she had cancelled offer on my request. I disputed this asking where in our correspondence I had requested a cancel and alternatively if a new offer could be made as there were no changes in their month offers. Emails to CUSTOMERCARE were escalated to RENTENTIONS and I emailed RETENTIONS direct. ABSOLUTELY NO RESPONSE. Request to escalate to supervisor ignored. In desperation I started again. Contacted RETENTIONS spoke to new agent. Went thru full procedure and was promised upgrade would be couriered 2 to 5 days and that I would receive a system generated email within 24 hours. NOTHING HAPPENED. Again emails unanswered. Even email to CUSTOMERCARE suggesting escalation to manager so I could discuss ignored. I SEE POSTING ON THIS SITE NOT RESPONDED TO. NOT SURPRISING HOW MUCH DO MTN REALLY CARE. MTN DON'T GIVE A HOOT
