Reversed claims

I been with discovery for year. And they was a dispute where they cancelled our membership. And we have agreed to payment discovery back for the funds I have used. Then they reversed payment to a service provider. The service provider claimed the funds from me which I paid. Now to get discovery to remove that amount from the funds I’m paying back to them is so hard but when they want their money from us. They will phone 10times a day. It’s been over a month and have called I have sent email with reference numbers but no response. Now I get an email stating the can not find the claim with the reference number. I need to send them me membership number or ID number but I not move a member because they cancelled membership for something that wasn’t a problem at the time of joining. Because it’s was under control. No one can predict the future.
