VUMATEL lacks customer service

I am extremely dissatisfied with the service from Vuma, I signed up with Mweb and Paid over 2 weeks ago, I have received no communication from Vuma for installation and I call the call center every day. It's either I wait on hold for a long time over 30 minutes with no answer, or i do get through and they tell me they will escalate it, no follow up after, even after requesting a callback on status.. leaving me calling back the next day. This is highly frustrating.
