unfair conduct and treatment as loyal customer

I am very disappointed on Standard Bank. I have remained a loyal customer for 10 years now. Even after they exposed my account to *****, I still stuck by them. I have app**** for various products and have not been granted any packages (car finance, personal loans, etc. But other companies have been able to grant me. I app**** for a homeloan with them and again they were the 1st to decline my application and other institutions were able to grant me homeloan. It sad how I found myself in debt through them and managed to stay clean despite this and to them long forgotten and able to judge my profile from far without taking such into consideration. Banks like FNB and ABSA look into their clients profiles and based on the way they conduct account offer them packages that suits they needs. I type this with a sad heart as I look at changing my bank that I have remained faithful to for so many years
