Unable to change membership from my deceased brother. Been sent from pillar to post

It is quiet disappointing and after reading the reviews I now understand that I am not the only one who is dissatisfied with the poor service. My brother has a service with vumatel - webafrica. He passed away on the 18th November. I have tried numerous times to move the membership to my name. You are never able to speak to a person over the phone unless they are calling you for a sale. There is never a manager to call you back. I have been transferred from agent to agent for over a week. Was asked to fill and send documents numerous times now forgeting the fact that i have to explain the current situation to every consultant i chat with. How difficult is it to move a membership and create a payment link. When a new sale is created you guys are very fast but the post sales experience is ridiculous. I just wish that this nightmare could be resolved as it takes hours and hours to even chat to someone
