General purpose card Managing, opening, or closing account Louisiana

This company is holding my funds in the amount of $3100.00 and my account has bwen closed for over 30 days and they still have n't sent my check they say they are waiting for some pending disputes to finalize but nowhere in there terms and agreements does it say they can hold your funds until it is finished. If I do n't receive my check in 7 business days I will file a lawsuit against american express for breach and contract and many other legal laws they have broke in holding customers money.
