No service from Rain

I first started using Rain in January 2019, I thought it was great. 19hours of unlimited data and the speeds were amazing. Unfortunately it was too good to be true, the whole month of April I've had intermittent service. Back and forth with consultants telling me to change the user name back to default (hasn't been changed from default), to reconfigure the settings (which I now do everyday 3/4 times until I can frustrated and turn on my Telkom ****le) and I filled out a Customer Complaint Questionnaire with all the information they required and now I'm waiting for a response with no service ?
