Bad bad service

Firstly after days of trying to connect to the internet we finally got access to internet. We then requested for a line speed change which was said to take 3-5 business days on the 5th day we get an sms stating that the account has been upgraded but yet when checking line speeds it still shows the previous one when calling in agents don’t know how to assist because it’s showing the new line speed then we called vumatel only for them to tell us that there were two ip and mac addresses when there should be only one. Called supersonic again and got told they’re forwarding this to their managers but can’t provide me with a turnaround time. I would love a response in how long it will take for this matter to be resolved because come month end you are going to want the installment for the upgraded line speed which is not on
