Rain, a totally useless network provider

I’m totally annoyed with rain. 4 days later and my refund is still not processed. I took out a line with rain upon checking if my area is covered and the big lie was yes there’s coverage. I’ve been so frustrated to a point of signing up with another provider as I work from home and my kids do online schooling. I went into their Roodepoort branch and they informed me the line would be cancelled, to my surprise on the 6th they took money from my account. I’ve been told they will not be able to refund me as the order date was for the 25th, the least would be pro rata which I think is unfair because the line hasn’t been in use. I need my money back because I find it ridiculous paying for services while I’m frustrated.
