5 months and 3 premiums changes no one has answers. Assessment completed before inception

I'm appalled by the level of service that i'm getting. In August last year I took time to sign up with Alexander Forbes. We had agreed on a monthly premium of R3000 for 3 vehicles with household content. By December it had increased by R700. I had called to add 2 cellphones and some all risk items which didn't increase the by R250. The most disturbing part of all is that in December I submitted a claim on vehicle. The authorization was quick and prompt but an excess of R10000 for a no assessment certificate was loaded. The worst part is that AF service provider came to my premises to conduct the assessment on all the vehicles. When I ask the provider for the certificate they tell AF has to logon to a system to pull the assessment certificate that AF has. Now I have to call AF again to amend this authorization. I called again this morning held on for quite awhile it's my time and money to resolve something that I shouldn't have been following up on in the first place. I have to call My Glass again should I have accident with the other 2 vehicles. I have to follow up again about the increased premiums and the claim with excess!
