Terrible reviews for Radiology. In spite of my sending letters disputing this account to the address on the invoice I received, there has been no response from Radiology. Radiology was also provided my updated address. Radiology referred this account to collections in spite of my letters requesting any and all documentation with regard to said invoice be provided to me and my advising that I disputed the account in full. Collection agency was not provided correct address. Would be interested to know how other individuals have handled this situation with Radiology.
