Unfortunately at this point in the game you will have to prove it.

Sounds like they got a default judgment against you so they are in a happy place and content, so its up to you to prove your dollar figure is the right one.

If you don’t understand the court system then my advise is get a paralegal if this is really worth the fight to you.

We have been disputing invoices from a supplier ongoing since we started buying from them, and as such have stopped purchasing anything. Last year, about this time, the bookkeeper decided to send the account to collection. We were not informed of this, and continued to send in payments to them, and attempting to resolve the issues. The collection agency never did contact us, in spite of having our current address and phone numbers. In August of last year, they claim to have sent a court filing to our previous corporate address, however, nothing was ever received by us. There was a garnishee on our account approximately 6 weeks after the court date, and that is how we found out about it. I contacted the CA - explained the dispute, made an arrangement with them to have 50% of the amount of court order paid immediately, with payments of $2000.00/month for the next 3 months, with a final payment of $820.26 in this month. Today's date the CA grabbed $6705.99 out of our account, on what the bank says is a court order. This however is impossible as I have not received any kind of accounting from the CA, the creditor, or the court, and I certainly haven't been invited back to court to dispute the original order. The CA is saying that THEY made a mistake, and unless I provide them with proof that my records are right then I just have to pay it. This is an overage of $3885.73 of the original amount the court ordered! The money is already out of the account! What do I do? In Alberta.
