No service/ no coverage / no help for three weeks

I work from home so when my contract ended with Vodacom and I immediately went on and got RAIN for Wifi purposes. I started using it in June 2019 and I was satisfied with it.. It was affordable and reliable for the job i do. On the 30th October I woke up to find my SIM out of service/no network. I reset the device, i reset my APN settings, I inserted the SIM in other devices but still nothing was helping. Because I needed to work, i went to my sisters place which is 15 minutes drove from my home and used their Wifi. I tried mine again and it work so i was sure everything was sorted. I'm at home the next day and again 'no network'. So my sister brought their router to my place to which their SIM said 'no network' too and that was then when i realized that I did my have coverage in my area anymore.

Day 2: I contacted RAIN and spoke to a consultant for close to an hour to which she was telling me to do exactly what i had tried doing. Nothing was resolved. I got disconnected because i was using data so when i got back on i spoke to another consultant to which i had to start down explaining everything. Again nothing was resolved. We just went back and forth basically. I was then told that this issue would be escalated to the NETWORK DEPARTMENT. Let me just say that the consultant coolant even find my location on her map until i sent her a screenshot of it. I then asked how long it would take for the Department to get back to me and i was told maybe 12 - 48 hours i was frustrated but I had no choice. I then went on Twitter and DM'd RAIN but then I would get responses hours later.

Day 3: I contacted RAIN and still had no feedback, i explained to them again about the coverage and what the other consultant had said. I was told that it is probably the Tower network that needed to be reset in my area.

Day 4 was Sunday so I didn't contact them.

Day 5: Was a Monday so i contacted RAIN again. And explained my issue again. To which the consultant said that my issue had not been escalated and that she would do it right then and there. I was mad at that revelation! The consultant then said she would send me my ref number via email to which she didn't.

Day 6 went back and then Day 7: I called and and asked for my ref then had to discuss this issue AGAIN. The consultant then said he would call me when he had feedback then gave me my ref.

Days turned to weeks! Two weeks... Still nothing.

On the 13Nov I contacted RAIN and sent them this message "Today marks three weeks without service on my side. My ref number is 615687 I haven't heard back from you'll. Is there someone i can speak to who will can give me answers" To which the consultant sent me a screenshot from the "Network Department" saying 'The client is not latched onto the network. She needs to set her APN setting' To which I responded I have done this a million times is that it to which she said I should reset my device and hold for 10 seconds which i had done everytime before I contacted them then she said she would re-escalate the issue and I asked her 'Is that going to help because it didn't the first time around' to which she said yes. I asked her what would be different now because they were suppose to reset the APN settings on the tower closest to me and didn't. Then I cancelled my SIM. I haven't used it since the 30th October and yet I paid for the entire November. I didn't get help! I'm so disappointed!
