Lecanto Surgery Center Told me the wrong Insurance co-pay and now I owe them $550 Lecanto, Florida

Lecanto Surgery Center was the place that was recommended by my husband's doctor for his prostate biopsy.  We asked them prior to the procedure what our cost would be.  They gave us a figure of about $190.00 which we paid.  Now we have received a bill for $550.00 more.  The doctor that sent us -- Advanced Urology in Homosassa, FL, had neglected to tell us this provider was not in network and neither did Lecanto Surgery Center.

I feel very ripped off because money is so tight and we never would have had the procedure done by either the Dr. at Advanced Urology or the Lecanto Surgery Center if we knew that it would have cost us this much.  My husband and I were both out of work for a long time and do not have reserves.  I called Aetna and they basically said Let the buyer beware.
