If one bank reject you , just move on to another. If you have the requirement, bank would definitely want your business.
Years ago i applied for RHB bank plat master and they rejected me, after 6 months apply again but ticked gold card and rejected again. My salary and company payroll is also at RHB. My credit record is definitely clean and never had any problem.
So i went to MBB and got myself a plat visa card on hand in less than 3 weeks. Today i have almost all major banks cards but still dont have RHB because never bother to apply from them again lol.
