Bad Service

I have never encountered a company that is so reckless and doesn't prioritise customers the same as home connect.,..I don't have WiFi the whole day and I paid but 2 month ago they disconnected me for not paying and I had to pay arrears to reconnect...but when I'm not connected they don't pay. How's that fair...the connection is so bad I'm spending R700 per month on nothing...the whole day I don't have WiFi their site shows I'm all paid up...I called on 3 different numbers it says I owe...how ?
