Vodacom is dying

Vodacom LTE uploads has always been a problem with this line. I expect 30MB up and down. I am only getting 7MB upload on a especially good day. Our server is in the cloud, so I need the upload promised to be on par. Then I log a call on Monday 12th May. With no callback or feedback I am start the cancellation process on Monday 19th May. Mind you, I have received three calls from Vodacom to sell me stuff, just none offering the requested support. Now Vodacom want to charge me to cancel their faulty line for which no one is offering support. I have quite a few accounts with Vodacom Business, and I won't be renewing a single one.
