Synchrony Bank Credit Card Complaint

Synchrony Bank Credit card department,

Credit line increase/decrease Pennsylvania

I have been making on-time payments in good credit standing with Value city for over a year. Last month they re-ran my credit score and based off that, they lowered by credit limit, - my score went down because I just purchased my home in - 2015. My issue is since they did that it has negatively affected my credit score because now I am using 77 % of my credit limit since the limit was decreased, where before I was at 67 %. Credit limit greatly affects your credit score. Not only did this do nothing for me but create negativity to my credit score, I am still making on-time payments and a great customer. They do not care how they affect people and the great customers they have.
