Call Centre Departments Working in Silos Game doesn't care about how efficient their services are

I get an SMS today demanding payment with a phone number. I call the number which takes me to the collections department. Collections department cannot tell me if my payment which was made 48 hours prior has been received as they cannot see my transaction history. Had called the collections department twice the previous day with no answer at all after holding very long for an answer. Had to be put through to the Client service department. Asked the client service consultant if they think it is ok that their departments are working in Silos. Client service consultant had no idea what that concept is so asked to speak to someone more senior. Was put on hold for so long that I had no choice but to hang up. I cannot wait until I can settle my Game account in full. I have stopped using my Game card due to service like this. Game doesn't care about how efficient their services are. Thanks game for poor and inefficient service.
