The worst internet provider in South Africa

I'm now 7 days with out internet because off a faulty modem. I only been with them 1 month and 14 days. Modem is brand new. It was every time escalated. It took them 3 days to decide that they are going to replace the modem on a Friday afternoon and it is out to be couriered to me. Monday got a mail that the courier is on it and will contact me. No one contacted me I had to phone RSAWeb again to find out. Then they said courier pick it up and wil be here next day. The next day 16:00 had to phone again to find out where the courier is with the modem. Then they checked and phoned back that it was rooted to wrong adres and have to wait until tomorrow again. After that I phone to cancel my subscription and they asked why I explained to them the whole story. They didn't even care that I was canceling and just said okay they wil log a ticket and just said "is there anything else we can help you with". This is how you treat your customers. They don't care
