bad service

I am very disappointed with Absa bank as I have been banking with them but do not take that into consideration. I have a prescribed debt with them of more than 15 years which is funny that they have given me a loan but when i apply for a credit card with them the call centre lady i spoke to told me this morning that it reflects that im on debt review whereas there's no such and how can 5 years ago account still pending? I bank with them and have a loan with them which i pay monthly very well. I have no choice but to take my account to where I will be treated as a good customer. they have declined me for a credit card. im sorry but I will cancel everything because clearly I'm not worth their bank.. If i was under debt review why did they give me a loan but now refuses me a credit card.
