Vodacom Backup Service

I have been with Vodacom since 1992. Currently I run four business accounts. For three weeks now and multiple phone calls and emails I cannot get technical service from them. They cannot link a simple one number request, and I've been paying for it for some years now. Every day its (can you give it more hours? ) It was escalated to the "back office". Why are they employing workers who cannot do the work. A massive level of incompetency in my opinion. I feel loathed but i think I need to cancel my accounts. Are there any others that have had this experience?
