Bad service

On the 29th of May 2025 i went onto the Rain’s website since i had connection issues to my surprise there was a payment of R478,17 that i had to pay, i proceeded with the payment and my connection was restored. Today my wifi was disconnected i logged into their portal and they advised me that my account is in arrears i owe R625. I tried calling their customer support line i was holding for too long, i tried reaching out to them online and they advised that i will get an email regarding R478,17 refund. No one has called me nor sent an email regarding my request. I am so disappointed in their service, its so bad
