unprofessional service

I am forever getting calls from Standard bank informing me i can increase my credit limit on my CR card Yesterday when i went in to increase my limit by R2000.00 . I experienced the following 1) The phone line system was down when it did come on i was put on hold for 34 Minutes by the agent i then put call down. 2) I called back and it to 20 minutes asking me questions like can they use my information or pass it on to their other department for marketing purposes ect ect Only after going through this whole song and dance i was told it cant be increased. I said but they keep calling me the answer i got was at that time the called they could have increased then but not now. Just very unprofessional of Standard bank and its no wonder they have to cut staff. I will be moving my accounts to FNB
