Mtn lack of service

I was ****** at knifepoint and my cellphone was ******. I phoned mtn direct from my daughters phone to block the sim and phone. The following day I went to an mtn store to do a sim swap, only to be told there was an "open ticket" and they could do nothing until the ticket was closed. I've been to two stores, phoned the customer care line, spoken to various managers and "service champions" who all promise to get back to me and then dont. I've sent messages on Twitter and received responses such as " call 135" or "visit your store", all of which I've done. I've also received several Twitter DMs saying " we assure you this has our full focus and we apologize for any inconvenience". It's 10 days now, I'm without a phone, I have lost all my contacts and I'm paying for a contract that I cant use. Frustrating does not begin to express how I feel. The trauma of being ****** was bad enough, but this fiasco just compounds the awfulness of the experience.
