NO SERVICE FOR A WEEK!!! NO RESPONSE!!!

I reached my call limit, I logged onto my profile and increased it so my line could be unlocked, received an sms as proof, a day later, my line was still locked. I called the call centre to advise them, they said off line and will call me back, never did!! then the next day, still off line, I called them again & was told off line still & that I must to go vodashop. I refused to do this as it is not my problem & I refuse to be inconvenienced. So they logged a call, to date no one has called me with an update, this happened on 21st Sept, it is not the 27th Sept. I cannot accept this pathetic shocking poor service, I have been with Vodacom a loyal subscriber for 10 years, I do not appreciate this service, I cannot dial out, I cannot send smses, I cannot use whatsapp, for A WHOLE WEEK & NOBONDY KNOWS WHY??!! Why am I paying a subscription if i have NO SERVICE? Rest assured when my contract is over so will my ties with Vodacom. I am shocked & this is unacceptable. I am paying for a service which I am not receiving. Please can someone urgently get back to me, I cannot be without a phone for another day!!
