L2 Computer Inc. Con Artist, Fraudulent and Exaggerating on repair Dones New York New York

We shipped our MacBook Pro A1260 Logic board for repair, and took them two week to work on it and shipped back, we installed it and the problem didn't get fix it's worst, call the seller and he/she asked as to sent the whole laptop, so we did.  They call back a little over a week later and ask for additional $85 to reload OS, I refuse to paid because I know it's not the OS problem, we tried to reload OS before shipping it out(our original problem was freezing up, check hard drive, ram, try to reload os but was not success). 

I purchased the repair service via ebay item #230700256468 for MacBook Pro 15" A1260 820-2249-A 2.4GHZ Logic board Repair Service, on 02-23-2013, got back the second repair attempt on 05-02-2013, but now it's just beep.  Before shipping back the item seller said she won't charge me but on my paypal account it's not being credit, call back 05-06-2013 seller change mind and refuse to refund.  I am now lost $169.96 plus shipping of $10.71, and my cost shipping back and for additional $50, so total lost $230.87.  I lost the money and time plus a customer.  This people is not professional, take try to make up problem and get more money from you.  I know because I am a computer repair technician we have two store location in California.
