InterFace Network No Refund Gaithesburg Maryland

They "found" my 14 year old daughter at Montgomery mall  on 1/25/14 and started calling us non stop. I went to the meeting the next monday 1/27/14 thinking that it was just an initial metting. I didn't want to sign the contract but the "Director" told me that I had 3 days to cancel the contract. The next day, I read the contract and realized that this was a shady business. I cancelled the agreement, sent it certified mail within the 3 days, I called and emailed them of my cancelation. they never called me back. The received my certified mail and I assumed I will get my money within 30 days as stated in the agreement. Today, I called to know whent I will receive my refund check; omg, this is the most horible business ever, they hung up to phone on me, put me on hold, transfered my call, blocked my number. I called the 7329934281 number numerous times and had the smae treatment. I finally reached miss Rhonda Johnson in customer care who told me that the office in Gaithersburg has not sent them the cancellation letter. I went to the local office and talk to Natalie was told to wait the 30 days, she didn't even look at my files. I am going to wait till next week and I will report them to the Maryland Attorney General if I don't get my money back. I will also call a private lawyer soon. I followed all the rules to get my hard earned money back and this people want to steal it. But I will never let them.
