Again... nothing from Vodacom... nothing but promises

USELESS... On the 10th I wrote a review here about my home internet speed (less than 10mbps connective when paying for a 30mbps line), and the absolute lack of service and understanding from Vodacom. Vodacom rep**** on the 11th saying I'd been contacted and that's it... BIG help if I've been contacted and nothing was done...I mean nothing. The technical department said they can't do anything till they review the connectivity in the area...YOU HAVE MY ADDRESS! Check the connectivity before calling me and telling me you need to check! And that's it....that's the "contact" I had. They promised to phone the next day to update me on the finding, and I would be home so they could do some line tests....guess what...no surprises...no contact since. I was told today on the Social Media (FB) support that they tried to call me today...THEY DID NOT. The number they "tried to call me on" is a line I use for work and there has been no calles missed, or any contact from them. Now what?? Must I be patient again...and again...and again...while you "review my case"?
