AVIOS CREDIT CARD and ABSA BANK

/ Madam In April 2017 i app**** for Avios credit card on line, my application was declined and after calling the number ***endless times , i gave up. A lady Called Elizabeth Mashigo advised me to reapply again, but NO REASON was given to me and nobody ever called me. On the 17 August 2017 i completed another application on line and once again was rejected , this time i keep on begging for a reason and nobody can help me with the reason of the rejection, nobody ever bother to call me. I contacted the head office of avios in the UK , they advised me the put a complaint locally and if i did not get answer to contact them again. I earn enough money to apply for a credit card, im not insolvent , im not black listed, i paid all my bills from A TO Z, no ******** records, etc. I have cridit card with standard bank. Any information is available on request. Can you please help me ? Shall i get a lawyer to represent me and take them to court? Many thanks Michael
