Credit limit increase fail

I received a call 2 weeks ago from Bluebean to offer me a credit limit increase. I accepted the credit limit increase and was told that the limit increase would be effective within 4 working days. <br> <br> To date, my limit increase has not been activated. I have made numerous calls to the Bluebean Credit Limit call centre, and each time I am informed that because I received a call from their campaign to increase my limit, they are unable to assist me and that they will send a query and request a response and that such response is to be received within 24 to 48 hours.<br> <br> I fail to see how whether I increased my limit through a Bluebean campaign, or through their limits department, this should affect my new credit limit to be loaded. Either way, my credit card is a BLUEBEAN credit card and it is BLUEBEAN who should be able to control the credit limit activations. <br> <br> I have found the service from Bluebean to be utterly useless and a waste of my time, and the fact that the call centre consultants will not give me the relevant details of the person to whom I can escalate my complaint is extremely infuriating.<br> <br> All I require is for my APPROVED credit limit to be loaded as it should be.
