BMO Harris Credit Card Complaint

BMO Harris Credit card department,

Billing disputes Wisconsin

We are - citizens, and my husband made a payment and by mistake he over paid Them by over - dollars. We have contacted them on several occasions asking them to please cut us a check we need that money returned and have been told that they ca n't they have so follow guidelines and we have to wait a month or more to get it back. Mean while they are collecting interest on our money and we are short money on our end. That seems very unfair. If we would n't pay them we would have to pay them a penalty. Is that rule reversed if that pertains to them withholding our money? Please look into this for us we really need that money back Thank your, - and - -
