Absa Creating expectations and then saying NO

I was offered a credit card limit increase up to R70000. My daughter has written off her car and I want to help her to purchase a second hand car for R50000. I called the credit card limit increase number *** and requested the increase. The lady who helped me told me that I only qualified for R39714 but because I am a pensioner who receives extra R1010 income from my niece and from my daughter I had to forward them letters confirming that this was paid to me. I got the letters and my daughter assisted me to send them to ***. This all happened yesterday just after 11:00. My daughter who sent the email let me know that she received an acknowledgement of the documents at 11:03. This morning I phoned the same number to hear what was happening and I was informed by Lungi that my documents were not received. She said that I needed to go to an Absa branch and resend the documents. I told her that I don't have transport and that I then received an acknowledgement of the documents sent, but she wouldn't hear me out and said that I must send the documents again. I send the same documents as sent yesterday to the same email address but this time from 3 different email addresses. My daughter received an acknowledgement of the documents received and I called the number again. After speaking to Lesego who really tried to help me, I was informed that the application expired and that she had to re-capture the information - after which I was informed that the application was now declined. How can Absa offer something, get me to do all the trouble to apply and then take it away. Absa is creating expectations and then disappointing their customers. I am not upset that I cannot increase my limit to R70000 as offered before - I am upset that they want to give me something and then take it all back. This is bad service and bad publicity for Absa!
