Rain *****ing money for wi-fi service not rendered

On 7 June 2025, I cancelled the wi-fi contract with Rain and returned the router at the Umhlanga branch. I have the cancellation number that I used to log a complaint when Rain debited premiums on my account this month. Instead of paying back the balance prorated, I was shocked that they continued to take money. In that last email I sent, they promised to call me back and to right the wrong. Up to now, no one has called me or reimbursed me.
