why doi have a platinum account but have no benefi

good day I have an absa account for a very long time. I have a platinum account aswell as investment accounts, I also have funeral policies at absa and I had my car insurance through absa. everytime when I ask for a increase on my credit account or a loan or a overdraft facility, I was NEVER helped. all other bank contact me on a daily basis to assist me or ask me to move over to them, but I always decline. why cant absa assist me, I always ensure there is money in my account, I don't go over my credit limit or I don't mess up my account. I pay fees in access of over R600 per month, but never did I complain. can I for a change get assistance for absa? what is the use of having this account, I might aswell have a normal savings account only then
