So disappointed in the Rain customer service

I have been waiting weeks for the accounts department to contact me. You debited my payment on 1st September but kept asking me to make payment. I called my bank and they said Rain had not taken the payment but the funds left my account. I called the contact center numerous times and I have sent my bank statement multiple times but I'm still waiting on the accounts department. I have been a customer with you guys for almost 2 years and had no issues until now. Now I'm down almost R500 and no internet!!! Are you going to give me a month free since it seems this is going to be ongoing until my next payment is due
