Sim deactivated because of Mtns fault and now I can't get hold of them

Mtn deactivated my zero rated contract because they thought I need a sim swap. I paid for the Sim swap see attached and then my old sim started working but then I moved me to prepared. I was refunded my money but I was account was never returned to what it was before. Mtn opened a case and till today it has now been resolved. They have also deactivated my prepared sim so I can't use it anymore. My whole life is attached to that number so I need it to be reactivated. I am living abroad so I can't walk into a call center. I emailed the customer care and didn't get a response. I tried calling +***7 which goes into a loop when I try talking to the agent and when I try to click reactive account it says the call center is closed. I even went to Twitter asking mtn for assistance but got no feedback.

I believe I have made sufficient effort to work with Mtn to resolve this issue but I have failed.
