Pathetic Service and Support

When we first joined HC the service and after sales was great. Where things went wrong was when we started receiving intermittent connection. There are days where I cant even join a online meeting without being disconnected once or twice in 30 mins. This is extremely unprofessional considering I can only work from home and the amount I pay for one of the highest internet packages. The issue is that everyone in the area and seems to be JHB is having issues with Vumatel but HC service team keep asking me to check my router and perform diagnostic settings when I log the same issue every few days!! Only to get told it an issue in the area and there is planned maintenance. I find this to be strange considering I have moved 2km away and changed my router twice but for the last 9 months I have had nothing but issues with HC and Vumatel. When will someone wake up and help the customers who are struggling to survive and have to deal with disgusting internet service.. To add to this the HC support team don't have after hours or do they pick up the call within 10 min of waiting and I cant count the number of times the calls get dropped.
