Received free annual credit report through Equifax and discovered unknown XXXX account. Called XXXX to inquire about this account, however, they were not able to find this account because Equifax credit report provides only first XXXX digits of the account number. Called Equifax to inquire about full account number and customer service rep, XXXX, said the only way she could pull up and release full XXXX digit account number is if I purchase Equifax Complete Advantage Plan. I agreed, however, after the purchase she informed me that she could only provide first XXXX digits, and not the full XXXX digit account number. This was completely misleading practice to trick customer into purchasing their product. They refused to provide refund. ( Spoke to the supervisor, XXXX, agent number XXXX - he refused to provide refund, instead gave me cancellation/reference number of XXXX )
