Webafrica LTE is effing slow and service is donners swak!

We got our LTE package from Webafrica. We run an online business and it is crucial for us to have a good internet connection. For the first month our internet was working fine, but then speeds just went down and down. I have already called and called and called over and over again to get this resolved. Every time I get told that there is nothing they can do it has been escalated to Cell C who is the provider. In the meanwhile we are paying for a service that we are not receiving. The ads I see of "effing fast" is effing ****ing me off more and more. We are supposed to get up to 50Mbps but constant speed tests never puts us over 2Mbps. Also our downloads fail and pages sometimes do not load. If I had a client that told me that their internet is crucial to the running of their business and called me day in and day out, I think I would give them updates as to what is happening and I would get on the phone and call Cell C day in and day out and demand that they sort out the issue. Since Webafrica is not resolving this issue, I will now go myself and contact Cell C to get this handled.
