Frustrated Customer

I have been using rain internet for March and it never gave me problems, but for the past 3 days, there was no connection. Today I decided to contact rain call center as now it's clear that we have a problem. I called them maybe 10times without getting assistance, using my airtime. Masinhle Makato decided to just send me a link, which did not work. I called again and spoke to a lady who at least was patient enough to help me create a new profile. The problem is that the issues is still not resolved, I work from home, for the past 3days, I was buying 1g airtime from MTN while I pay Rain R479 every month. My account is up to date, which is not fair. They keep on saying someone from the technical department will call me back. I just need this issue resolved.
