I don't expect BestChange to do this. They are a well-established company and have a very good reputation in and outside the forum, but you may not have met the requirements for the claim as in the quote:
When creating a financial claim, please make sure that the exchange regulations specified on the website ImExchanger have been violated and that you haven't received funds for the order. Please note that the claim may be turned down in the following cases:
The regulated exchange period has not expired yet.
The exchanger's regulations were violated. For example, the incoming transaction did not pass the AML check.
Be sure to indicate the exchange order number. It will help the ImExchanger administrator resolve the problem more quickly.
If you didn't like the ImExchanger's service and want to write about it, use the review type.
Are you sure you met all the requirements for the claim? And yet it was deleted?
