unfair treatment and angry customer

I have called ABSA credit card on the 28th around 10 am my ref for the call is C***1 and advised by the consultant I will get my letter that state my credit card is up to date, now when I follow up with Daren who put me on hold forever refused to transfer the call to superior and other consultants dropped the calls in my ear. I am so angry and disappointed at the treatment I am getting I feel like paying off the card and closing it I have never seen such an unprofessional bank in my entire life but when they call for payment they will call you the whole day. it is so painful that my spouse called last night but has received his letter today around 10 I cant wait for 1 o'clock I need it now or else my application will be declined I am beyond angry I hate this bank
