Frustrated and disappointed with RAIN NETWORK

I've had problems with this network since December 2019!!! At first, it worked perfectly. From June 2019 - December it was great then it stopped working. I just woke to one day and I had no internet access. Keep in mind that I run my own online business so I rely on the net for everything. I contacted RAIN and no solution was brought forward leading me to cancel the SIM. A few weeks later my sister who also had Rain was at my place and the network picked up on her SIM so I decided to order a new SIM. I had hoped that everything would be smooth and it was for a second. 10 February 2020 a day before my birthday around 15:00 it stopped working. I decided to knock off because I was anyway tired. I tried getting it back online but no luck so I contacted RAIN.... ONCE AGAIN - NO SOLUTION!!!! One of the many consultants I spoke to asked if she could order me a new SIM to which I agreed. The SIM arrived in a few days and I set it up.... BOOM it's not working! I then gave it a day and it worked.... Two days later it completely stopped working up until today I have no internet access. The consultants keep telling me the same stories, 'check your APN settings, restart your device, we will escalate this issue' blah blah blah!!! NO SOLUTIONS. At this stage I am frustrated and having to 'Chat' with them almost every day for the same reason with no solution is discouraging my hope, piece, and patience. Fix your stuff RAIN. If your network is working a specific area stop forcing it and let us know so we can cancel and move on tog
