Shocking service

I submitted 2 invoices for processing for reimbur*****t and with 1 of the invoices, I submitted a proof of payment. I received an email this morning informing that these claims cannot be processed as I have submitted only a proof of payment with no invoices. I have checked the original emails and there are 2 claims attached to it. Please sort this out immediately and make sure that you the right quality control in place! This is shocking from BestMed!!!
