***** and bad service since 5/1/2016

I get sms that my phone is in Lesotho. Not the case. Get sms that my sim card is used in a new phone. Don't have new phone. Don't receive smses. People that phonw me get through to strangers. Reported issue since 5/1. Vodacom agree ***** could be involved. No response to resolve issues. Get suggestions on how to fix sms that I do not receive. No improvement. Lately my calls get dropped. Frustrating if supplier hold contract date at you, but provide bad service. Have had no response on whether my account with Vodacom is correct. Jumps from average to R3000 . Please help. Their call centre incorrectly lock call detail. Get agents that don't listen. Not possible to get a supervisor or escalation done at 082111.
