Shocking service

I’ve tried to increase my credit limit since Monday 7 May and have been given the run around. I’ve submitted all the required documents 5 yes 5 times and I’m still being told that they haven’t loaded or received it. I’ve spent more than 1.5hours on the phone and who knows how much on airtime. Every time I get a different excuse and empty promises. I was promised it will be done on Wednesday the first time. We are now on Friday afternoon and still nothing. During my last call I was told it will be ANOTHER 4 days!!! How can you treat anybody like this and do you really care so little for your customers???
