30 Years of loyalty

I have a Sole Proprietor Account and have been with Std for 30 years, about 2 years ago I went to open a private account, I was told not to worry because the existing account could be used as a private account as it is in my name. I tried to open a credit card online but was declined (business account) and I must go into the bank... I went into the bank, after sitting for over an hour I got to see a banker who said I cannot get a credit card and must now get a letter of solvency from my accountant, they could then change it to a private account and I could then apply for the card, I have never been in debt and never had a credit card but thought I would get one just as an emergency backup because I am going overseas. Needless to say I walked out feeling upset and humiliated, after having such a good track record, this is what I get. I was going to get my forex but landed up walking out the bank with nothing but egg on my face. I am now closing my accounts at Standard and moving to FNB, I got a current, credit and savings account, when I asked how they could do that all, I was told my credit rating is excellent... so good by Standard Bank my accounts are closed.
