Fiber activation lack of service!

I had made pre-arrangements with my ISP (WebAfrica) to "Move House" with regards to my Fibre internet package-this was two weeks prior to moving house. The new premise already had a Vumatel fibre installed. I was told it would be a matter of Activation and boom! All that is required is to ensure the previous Fibre Account owner had deactivated their line. I had made these follow ups with the previous tenant personally as WebAfrica would not do this because the person was with MWEB. As frustrating as this is, I eventually got confirmation from the person himself that his line had been deactivated after he confirmed with MWEB.

Well, 7 days after being patient with WebAfrica and waiting for response as to why my fibre internet was still not active, I decided to change ISP to MWEB. Now the salesperson from MWEB was all to happy to say that it would be as easy as deactivating the old account owners' line (they phoned and got confirmation to from the old account owner) and make my account active- this is an automated process which should take between 24-48hrs. Well I guess this "automated" process only works within business hours, because 64hrs later, after an entire weekend, I have to phone up MWEB to get an update, just to be told that they will follow it up and revert back to me within 48 working hours.

Please explain to me, why 10 days after I have consistently been on the phone to Webafrica, Vumatel and MWEB, is paying customer still without internet access?Why is this such a tedious and loop-holed process. Why is there no customer care or even a follow up on the progress or status of the "NEW CUSTOMERS" products?
