Telkom doesn't want to help

For 9 months, I have been able to get LTE coverage where I am staying. From 1 June 2019 I started getting notifications that I must sign into telkom. When I tap on the notification it says I'm using out of bundle rates but I have data. All of a sudden I start noticing that I'm roaming on Telkom. I called into customer care and they didn't even believe that I was roaming on telkom and started arguing with me saying I am a ****(still shows that roaming on telkom). I called in countless times and kept getting different stories or what to do but nothing helped. Called in earlier today and was told that I don't have coverage in my area(So what happened to the coverage I had?).

I was told that there was nothing they could do for me since there's no coverage and I should just spend more on all network data. Really? How can you tell me there's nothing you can do if I had coverage for 9 months. I am unable to use the data I have on my phone and that I purchased!
