bad service

am still without internet after Rain debited my account and still asking me to pay as it is not reflecting,i dont understand why is that my problem because the money was debited and it is in their bank account they know my bank details as to where to debit but they are unable to allocate the payment and open the line i must send proof of payment meaning i must go to the bank and print statement buy data scan and forward the pop this is very frustrating and irritating on top of that i must buy airtime to call customer service,no man what kind.of service is this
