MTN cannot generate an invoice

Did not receive an invoice for one of my contracts for June. I have tried to send emails and call the business call center. This afternoon I spoke to a very rude call center agent that kept on interrupting me and argued with me. Then she told me the system was down. I went to the MTN shop in Clearwater mall where I was met with ***********, disinterested staff. Only to get told that they cannot give me an invoice for that account as there is no invoice available for June.

I have been an MTN customer for close to 20 years, both personally and in businesses I own. Not anymore. Your rude and *********** staff have cost you a customer that has been loyally spending a lot of money at your organisation for years.
