Discover Credit Card Complaint

Discover Credit card department,

Transaction issue Missouri

I have been trying to dispute several charges on my Discover credit card and after the last time I contacted your agency Discover opened the disputes and told me that they had issued provisional credits and allowed the merchants 45 days to respond or the credits would remain permanent. Two merchants provided responses that I am refuting, however, I have not heard anything on the remaining charges since. I would like someone to communicate the status of my disputes with - on -/-/16 in the amount of $500.00. - on -/-/16 in the amount of $5500.00 - - on -/-/16 in the amount of $270.00
