Continued debit orders after cancelling data use plan

Hello Peter, I wish I could make a positive review, but unfortunately, it is very negative based on personal experience. I have been subscribed to Rain Network for at least 4 months, for data usage. I have one of the best routers in the market. Unfortunately, Rain proved to be less effective, despite having undertaken a diagnostic test to check if there is connectivity in my area. I decided to cancel my unlimited data plan in early March. Since there is no contract, there is no notice to be served. The message I received was that the final payment would be at the end of March, based on the data I used. Since I did not use any data, I plausibly assumed that I would not be debited at all. Surprisingly, I was debited with R479, as if I was subscribed to the plan for the month. What's worse is that the sim card I canceled is not appearing on the platform, yet there is an invoice that confirms I used zero. Also frustrating is the fact that the system is showing that my next debit order date is at the end of the month. How so if I have canceled the current plan and have no sim card in use? Is this the reason why we now have internet providers that do not have walk-in offices/ points to resolve our issues?

It would be an inconvenience to cancel my credit card because of possible pending debit orders that I am not receiving service for. Again this makes customers more skeptical of service providers that are physically present to engage when there is a problem
