Poor & unprofessional service from MTN SA

Good day, As an existing customer of MTN we are currently receiving very poor service. Our reference number for this query is *** We were first supp**** with an incorrect product. This was about 6 weeks ago Then a replacement product was supp****. It took almost 2 week for MTN to courier the replacement product to us.MTN said the replacement would be the solution. However when we checked for the requested fixed IP address, we found out that we were infact given a dynamic IP address, which meant we could not use the solution provided. Upon the suggestion from MTN that a supervisor from the technical department would contact us to assist, we decided to try one more time. We are yet to receive a call from anybody from their technical team let alone the supervisor. It has been almost 2 weeks that we have waited for the call. We have issued instructions a week ago for MTN to collect the router and SIM that we cannot use. We are still waiting for the collection. I have sent numerous emails complaining to various people only to be pushed around from pillar to post. Now MTN resorts to just not replying. Very unprofessional. Below is a list of people I have contacted relating to this query: *** *** *** *** *** Eunice Shabalala Adil Haffejee I would appreciate if someone can assist to have the matter resolved.
