Credit Card Limit increase

I am please to announce African Bank always go extra mile. I received a call from them checking if I can qualify for a loan or credit card limit increase, guess what I qualified on both & payment was done in one day after submitting the documents. if you are a good payer on your monthly instalments, you qualify for more discount....I was shocked to be told my limit has been increased while monthly instalment dropped by almost 20%, on top was told that I qualify for the benefits since my loan was over R25000, was told a sim card with R100 for 24 month will be couriered.
