2.2% interest rate increase on my credit card in 5 months?!

<p>After numerous conversations and promises that they will adjust my interest rate and contact me with answers, I have not received any complement worthy service for almost 8 months now.</p> <p>My interest rate on my credit card has increased from 18.80% in November 2015 to 21% in April 2016. That is an increase of 2.2% </p> <p>in 5 months. </p> <p>Nobody can give me answers on the matter of why it increased so drasticly in such a short period. I have an above avarage credit score and have never missed 1 payment. </p> <p>I have been told that it went up because I only make minimum payments (not true) even if I have settled this account 2 times this year.</p> <p>In April 2016 an email went out to say that if you have a interest rate of more than 21% it will be adjusted to the now maximum of 21% according to the NCA. My interest rate at that stage was 20,45% and with the new credit act the increased it once again to my now 21%. How is this fair? I am a good client and they repay me by increasing my interest rate, again????</p> <p>I want a decrease in interest rate and I want answers on why it increased so drastically.</p> <p>Appaling service, sies!</p> <p> </p>
