Most horrible service provider

I have got a 20m download and 10m upload deal with Supersonic/Vumareach. I work from home and depend on this as a means to be productive. I have not been able to work at all over the past 4 days due to not receiving the required download speed I pay for. I used the link provided by Supersonic to check the speed and the result was pathetic my line speed I am running on is 0.49 not even 1megabyte and the package I am on I am due 20megabytes per second, I have been calling multiple times using my own resources, I have been made promises of technicians coming out and that I will receive call backs to inform me of any updates no calls received no technician no possible answers on what could be the problem

Supersonic/Vumareach is not willing to service you, I have been down for 4 days and they won't reimburse your money you paid for the monthly subscription. They put you through to technical support no assistance you hold for hours no callback and the WhatsApp chat is a load of bull**** Supersonic/Vumareach is a horrible I won't advise anyone to use there service
