Poor customer care

I've used vodacom as my service provider, same phone number for more than 14 years. During those years I was on prepaid and everything seems OK until I decided to go for only SIM deal on the 3rd January 2018, then on September 2018 they added 2 deals in 2 SIM-Cards numbers without my consent on top of the first one. I only noticed after the debit order was made, and I called them(vodacom) and they told me not to panic they'll fix the problem they suspect a ***** but I must do an affidavit with my I.D copy and send it to *** and I did exactly what they told me, only to find out the email address is no longer active, and now they decided to deactivate my phone number and I went to vodacom nearest branch and they said my account has been handed to lawyers, they tried to assist me by calling 082135. But I couldn't find help, and in that branch they knew everything bcause I always go to them, and they always say on branch level nothing they can do. In all what was happening they never contacted me. I WILL NEVER RECOMMEND VODACOM TO ANYONE, instead I'll warm them as I was always warned but I was stubborn.
