Poor customer service

I app**** for an increase on my credit card on Friday the 27th of February, I was told to send through the correct documentation(which I did an hour after speaking to a consultant) and my application would be processed and done within 48 hours, I gave it some time until Tuesday thinking that maybe because it was a weekend I would take it as the 48 hours being Monday and Tuesday, I phoned the call centre this morning, after being transferred a couple of times I got through to a lady by the name of Brandy she checked my profile and said she will escalate it and it should reflect in half an hour, Half an hour sounded abit too fast compared to the service I have received prior to this, so I confirmed with her on YOUR RECORDED LINE that it would definitely be today, I didn't receive any feedback until 2pm I called in again I was advised by a lady that i was given incorrect advice as escalations take 3-5 working days, I am not happy at all with the false information and poor service I received as a client and I dont feel it is my job to sort this out, Quick to give credit but when a client is in need of help no one can assist.
