RCS laziness.

This is in regards with my wife's RCS game account. Well she made an online payment once. After a few weeks she started receiving threatening call from RCS, of course the payment wasn't reflecting yet. She sent them prove of payment but they kept on phoning until they eventually recieved an email stating everything was in order. 2 weeks ago she went in and asked for credit increase and they said no because of a late payment not one time did my wife ever miss a payment.An online payment that took forever to reflect now she is at fault not fair at all. The people that phones is uneducated and rude. I told my wife to pay that account finish no business from our side again sorry in this day and age you cannot deal with such illiteracy. To make matter worst they tell her to phone in 4 months again what a ****m joke.
