Worst Bank In S.A

I have been contacted by absa nearly every month to increase my credit card to 100k limit but every month they decline me , i ask why? they say affordability. i tell them that is impossible i have no bills going off my account , then they cant answer and just tell me its the system. i made 3 complaints in 2 weeks and not one person came back to me. so i called again and spoke to a lady and she tells me that back office has had my application for the past 2 weeks but Buitumelo Vister doesn't do her job to contact me for my supporting docs so i decided to send them any way to limit increase. one week later and Buitumelo still hasn't contacted me but when i call the call center they tell me my documents is still sitting with Buitmelo Vister, when i ask why is she not doing her job and contacting me no one can answer me. Why is this Buitumelo person acting like they so special and doesnt have the decency to contact her client after i have sent all the supporting docs, why does she keep declining me and not contacting me about anything when i can clearly afford this credit card after she has seen my supporting docs that i had to send myself because she was to lazy to ask me for them. Does absa know what kind of bad staff they have and what kind of terrible service they give clients. They sit with my application and don't contact me even when i leave 100s of messages to contact me. worst of all when i go in the bank they tell me to wait for the call center to get back to me. This bank deserves junk status. Truly the worst bank in S.A they dont give a damn about any client
