RCS missed payment and has not allocated it for over a month

<p>I made an account payment in an RCS approved store on the 6th of January, somehow this payment was not picked up on the system. I then received a very rude phone call from the accounts collections department on 18 January to say I had not paid my account. I sent the receipt via email and immediately called the customer service department to check that it had been received which it had, I was told it could take up to 7 working days to allocate the payment to my account. I have called back twice since then and the amount has not been allocated. No one will call me back they keep telling me to call back to check on it and that they cannot contact me which is absolute nonsense if true. Every time I call o spend no less than 20 minutes on the phone most of which is on hold listening to ********** music. Can someone please address this? I'm beyond fed up</p>
