Citibank Credit Card Complaint

Citibank Credit card department,

Credit line increase/decrease Florida

My credit limit was reduced, due to errors on Macy 's part. I have paid off my balance month ago, but due technical issues on their end. I was charged fees, and not notified of changes. I called to get fees waived on this past Saturday, and now today I get a letter stated my limit is being reduce, which will effect my credit score. I want my credit limit restored.
