Still no help from anyone!!!!

Good Day. I have exhausted all channels of communication, and I'm resorting to Hello Peter for the second time in 2 weeks because my issue has still not been resolved, and I have not been contacted by anyone. The store manager has been absolutely poor in resolving the matter, does not return calls and is now not even taking calls. I haven't received any responses from your Twitter account, Facebook account, Site Complaint portal and Contract Customer portal. My previous Hello Peter report was responded to via one call, and I was promised feedback but I haven't heard back since. It's almost a month that I am awaiting activation of a service that I paid for, and Mtn has not come to the party in terms of honouring this service, nor in terms of its after sales service. This is extremely poor service standards, and is unacceptable. Please have someone senior who is responsible for customer service contact me urgently.
