RAIN debit

I was billed a sum of R147.37 on 01 March 2021. As far as I understand, the first month of my 5G home plan is paid up-front, thereafter I will be billed at the end of the month. Thus I should only be billed R699 at the end of March / start of April.

I also had a 4G plan, which I paid up-front, and cancelled within the first month. Thus I should not have incurred any additional charges, as this sim card was not used at all after the first month.

I am very displeased with RAIN and want a immediate explanation as to why I was billed, as well as a refund of R147.38. I have only received poor customer service up to now, and even worse internet speeds. Browsing speed is fine, but downloads are throttled. This was not what was advertised. RAIN is the absolute worst ISP!
