Billing process sucks!

I recently started using RAIN and I liked it for the first month, the problem started month end,I noticed that the next package was going to be debited so I waited for the debit order date,but nothing was debited,I went into the account and noticed that they have already created a billing record for me to pay which was confusing because they said they will debit I then went ahead and payed and its like that payment was for another sim card, which also doesnt make sense why I would buy another sim card inside an account of another sim card They ddnt also specify that the next payment will be debited,Now I have an invoice that doesnt make sense and when you call them nobody picks up the support line and the sales line is useless they cant help you with anything
