AGAIN Vodacom penalize me for there mistakes !!!

Added bad review last year due to Vodacom billing me R13000 plus for a 3g account that went over the allotted 5gb monthly cap. When I took out contract stated that I want it block as soon as it goes over limit , and was told it was setup. Obviously was not done and had to put in a Hello Peter review before I was eventually refunded, but now they have blacklisted me because of that??? I cant take out a account due to this issue, it is ridiculous as it was there fault from the start!!!
