Worst service ever

I have been trying to get my line connected since Monday 22 May after I requested a downgraded to a 40mbps line and paying the R499 via the easypay sent to me at. Pick an pay after the downgrad. First of all I use the whatapp, email and live chat and no one responds. This is ridiculous to know that Me as a client gets treated this way. I cannot understand the rationale off not haveing a call center to call or even for one of the call agents to call back. This is a very frustrating way of communication to get a problem resolved. On live chat , at the beginning it says that there is at any given time maybe 1 to 6 agents on line but one has to wait very long for a response. Then we get the sorry for the delay as they are backed up. Only obvious you will be backed up with so little agent on line. I would therfore ask if the R499 I paid could be refunded and I could rather use another ISP that treats there clients much better. They are not supplying me with a service that I have payed for therefor in breach of contract. Never mind asking to be compensated for the lost days. Please refund me so I can take my money elsewhere .
