BAD CUSTOMER SERVICE, PHONES BEING CUT OFF

I am using MWEB as an ISP, they are very terrible and horrible at reaching them telephonically. We added a DSTV package in Feb, only received an SMS in April that it is activated but yet it was not activated on the channels that we requested. We have since been trying to contact MWEB to sort it out, they confirm to have it sorted but not. We are billed with a service we did not receive, each and every time we call, it gets hung up as soon as we verify our details. This is not the first or second time we have difficulty reaching them and it is so frustrating to deal with such. It's exhausting dealing with them, just a bunch of *********** people!
