Fibre dead after upgrade request

Requested upgrade of Openserve fibre line from 40mb speed to 100mb speed for which Webafrica are my full ISP (reseller of Openserve). I am charged immediately for the upgrade. Within 12 hours of the upgrade request, my fibre line goes down, no service at all. I am still without internet service. Webafrica blame Telkom/Openserve and CLOSED my support ticket! Still no internet. I get hold of their online chat service. Get told someone will help. 2.5 hours later, still waiting on the chat service - further requests ignored. Get hold of Webafrica on Facebook. They tell me someone will assist me. Still nothing. I call Webafrica and am told to phone Telkom/Openserve myself (But Webafrica are my ISP, I pay them for all my services - they should be phoning Telkom!). I phone Telkom and after 25 minutes and 3 different calls (10210, 10217 and 10213) I am finally told that the problem must be with Webafrica, not Telkom/Openserve. Enough is enough. You've billed me and now I am without fibre service at all!!! The customer support from Webafrica is utterly atrocious. Someone better get this resolved immediately.
