SAIS I WAS APPROVED BUT ACTUALLY WASN'T!

On Monday i app**** for a credit card limit increase of R 15000 on my online banking. It gave me a message saying that i was provisionally approved. I then phoned the bank just to make sure that it was received, as i needed it for a deposit on a property. After holding the line for exactly 48 minutes, a lady answered and said that the application is underway and to speed it up i need to send copies of my 3 latest payslips, which i immediately did.<br> She then told me that it takes 24 hours before i get a notification and i told her the amount i app**** for etc. Today, i received a message saying that my limit increase has been approved. I logged on to my bank, to see that they only deposited R 716.44??? I phoned back, stayed on the line again for 57 minutes! She then said to me that they only deposit the amount i qualified for???? BUT THEN WHY TELL ME WHAT I'VE APP**** FOR HAS BEEN APPROVED?? There was NO communication to me saying that they will deposit that amount only, OR EVEN HAD MY PERMISSION TO DO SO??? If i wanted R716.44 i would've app**** for that!! IF SOMEONE DOES NOT QUALIFY FOR WHAT THEY HAVE APP****, HOW CAN YOU SAY THEY'VE BEEN APPROVED??? I am VERY upset about this!!
