Rain inadequate service

I use Rain Wi-Fi data, and I have experienced some problems with their service.

1. The only way to get in contact with Rain is through their website or an email. Their response to emails are not good.

2. I have been double-charged for several months. On the Rain website it appeared that we have 2 sim-cards and were therefore charged for 2 uses at R479 per month, thus R958 per month. We have no idea how the second sim-card came about, and we never used it, but we struggled for several months to get the service stopped.

3. Rain only allows certain dates for debit orders, which does not correspond with our salary date. We seem unable to change that date to a more suitable date. This causes the payment to sometimes be reversed due to no funds in the account, and we then just pay it once there's funds in the account.

4. Rain now claims we have not paid them since October 2021. I've sent them proof of payment via email, but they refused to accept it and wanted a copy of my bank statement for the period, which I provided. My service has still not been restored.
