Complain about Service

We woke up to Rain Network bad service. Our WIFi is been cut of and it's not even month end. We called them and they just demanding payments as if we are in areas. This is bad because we haven't even received our salaries. I send email this morning to support. They respond to me with contact details and their number are not going through. Both Capetown number it ring once and it get cut off same with th one they provided on email. This is not fair at all.
