Rain wifi cancellation co.plaint

In the beginning of May I contacted Rain and notified them I am canceling as at the end of May which is within my so called cycle through their whatts app and tele phonically through their incompetence they did not capture the cancellation request and the pick up of the router the Rain remained active despite me calling them sending numerous whattsapp evidence that the confirmed the cancellation would take place as at the end of May Rain goes ahead and debits my account with R620 for June after speaking to their robotic consultants who have set scripts keep logging tickets now I have a bunch of tickets logged but the cancellation according to them was not captured on the system requested to speak to management total blabk but when I call and select option for billing wow suddenly they answer the call and yet another ticket Rain will never be my choice of service provider for wifi nor will I recommend to friends and family I still await my refund
