Terrible Service again and again

Earlier this month we bought Vumatel to be our service provider, and in the 3 week since we have been with Vumatel our internet has not worked for a total of 15 days. On 3 separate occasions the internet line has gone down and each time we have attempted to log a complaint (nearly every call we were put on hold for roughly 20 min) we were essentially **** to. Each time we were told that someone would arrive within 24 -48 hours and on each instance we only received assistance 60 hours after logging the complaint. We were also promised that someone would phone us on the update of the status or the ETA of the maintenance arrival and not once were we phoned. This shows a lack of professionalism and a lack of care for their customers, we are currently looking for a new service provider as Vumatel still expects us to pay this whole month and not compensate us in anyway, as we lost business through the internet shortage. I hope a drastic change occurs and that no one else deals with such terrible service
