9 Days Without Service and expecting longer delays

Now 9 Days without service. Hours on phone in waiting queues and hundreds of Rands of phone calls. Numerous tickets created and just told that the issue have been escalated. had a call once and there was a replacement of my Fibre converter, but still no service. I run a practice and am dependent on the service. I dont know what to do anymore, but to cancel my subscription and go with another SP.
