African Bank Sales department worst ever experienced

I am utterly disgusted in the level of service received by the sales department staff of African bank. How can a credit card application take 3 weeks to even just get an approval or decline. When I call it's a document that is required for 3 weeks this has been going on and it's really frustrating me now. Back and forth sending letters and statements and the each new person requires some new piece of document. I have had it with the **** service from your entity. You need to learn to make follow up calls please, why as a potential client must I keep calling to check if your staff has been doing their job. Management please take your staff to task you are losing business.
