BAD SERVICE FROM FRNCHISE OF MTN AND MTN BUSINESS CUSTOMER CARE LINE

We have requested to upgrade our account from Dec 2020, We found our around middle Jan 2021 that the upgrade was not done as requested , From around 15 Jan 2021 to 15 Feb 2021 we tried to resolve with the franchisee and they could not give us a suitable resolution to the problem , and kept on blaming MTN Head Office . On 15.2.2021 I contacted Mtn Business Customer Care line on ***, that was a wasted day , as tow consultants took my query and promised a manager or senior person will contact me , but that did not happem , at 16.45 pm on 15.02.2021 . I sent an email to *** , and recieved a reference number and email that my query will be resolved in 24 hours , Today is the second day , my query is not resolved. I have now called again and requested for a manager to call me , I now have a list of the wrong package that was upgraded , on all our business lines , |I hope and pray they call me to resolve this
