Daylight ******* by Rain.

I am very disappointed at the way Rain has handled my complaint regarding a service I cancelled in May 2023, and I was told that the cancellation would be effective immediately. I have requested the recording of when the services were cancelled when I spoke to the consultant earlier this month and they did not send that. I never heard from them since the last interaction I had with Odwa on the 12th of June 2024. Prior to the cancellation I had multiple calls to rain advising them that the Wi-Fi network was not working, and I continuously expressed my frustration with them. Is there a regulatory body I can escalate this complaint to.
