POOR CONNETION AND LACK OF CUSTOMER CARE ASSISTANCE

I have been using Rain Wifi for almost 3yrs now. For the first 2yrs I had minor connect issues,but for the past 3 months it has gone from BAD to WORSE. And the upsetting part is that, when you call their call center you wait for more than 5minutes before you reach an agent (if you're lucky). I am using this Wifi for work purposes, so when I can't do my work properly that puts me in a difficult position @ work. My company already doesn't approve of this service provider and now, I am having extreme network issues and I can't even get hold of someone to assist me when I call them or let me know what is going on. I am paying R570 for this connection and it just keeps getting worse and worse. I AM NOT HAPPY WITH THIS @ ALL, COZ IT COULD PUT ME IN A VERY BAD POSITION WITH MY JOB
