Deleted my number, stole my credit and now refusing to help me

Once again Vodacom have stopped my SIM card and ****** all the credit on it. They have stopped this in error as they did a year ago. I had to go to hell and back last year to get them to reply and eventually they gave me a new number to fix their error. I lost a number I had for many years, this caused significant stress. They've now deleted my number again, leaving me overseas, stranded with no cell phone. Their e-service team refuse to assist me or escalate my complaint. Their Twitter team ignore me then use delay tactics like asking me for a number they can contact me on when they've deleted my number! They refuse to contact me via email or put anything in writing, Vodacoms usual tactic so there is no paper trail and they can lie About what they say and do
