Pathetic Service - No Customer Service whatsoever

Continuous Dropping Line in Marister, Benoni. Constant calls and live chats to try and get resolved, promised of being called back multiple times with no call back at all. Has been three weeks now with no feedback, constantly asking to test connections and multiple other exercises with no resolve. Requested technical manager to send someone out today, no contact, no technician, no anything. A company very quick to sign you on and debit your account, but when it comes to customer service it is absolutely pathetic. I have never in my life encountered such a pathetic service from an ISP, the others actually help.
