Rain Network is actually very dry !

I joined Rain's network last year to cut data costs as a student and at the beginning of the year I hardly struggled with connectivity. I chose a package that best suited my pocket which was the R250-00 off-peak hours data plan and I have not upgraded this deal ever since. I then experienced a lot of network problems as the year progressed and I assumed that this was due to a lot of people have opted for this network with their cheap deals. when 2020 ended I had already been in search of a better network provider because I struggled with my classes as the network would go for hours. I then decided to leave Rain at the end of January 2021 and It was to my surprise when I got debited an amount of R321-00 beginning of April 2021. I logged a complaint via their website and they said an agent would get back to me within 24-hours. I have since not been contacted or provided clarity on why I got debited for a month-month Simcard that I had canceled and had not been using for March. I am also struggling to get their contact details and I want people to know that the network has failed to keep its end of the bargain, I canceled the Simcard twice and I received an email saying that I will be debited again for the last time in May. This is is all for a Simcard I no longer use and a network provider I regret joining or buying into
