Wrong information

I signed up with Rain after I was informed that its a month to month WiFi but after I couldn't pay last month I kept receiving bank notifications stating that rain cannot receive funds in my account. Then I started receiving calls and whatsapp messages. On the call i was advised I owe R180+ because the service was not closed on the date of my missed payment. Then I advised I want to cancel everything. Which the caller didn't do yet she advised she did. Month end May by the 27th to be exact, an amount of R625 was debited instead of the R180+ that I was told about. Received another call which then I got a ref number for cancellation (***2) and was supposed to get my refund from the R625 deducted from my account without receiving Rain service last month. I was also advised I will get feedback within 72 hours. I then emailed them for feedback but still no one is getting back to me. I will never in my life recommend Rain to anyone
