THEY DONT KNOW WHATS GOING ON

on Monday I app**** for a credit card limit increase, firstly the process takes forever and they require an arm and legs worth of documents, they straight declined me then I appealed as that made no sense.<br> today I get a sms saying that I am pre-approved?????<br> when I call the call center nobody can give me a straight answer of a value and when it will sorted by...no other bank takes this long to process a limit increase this is ridiculous and further more the staff have no idea what's going on!!!!
