Great Call Great Call Splash, Jitterbug Took my money will not refund when non working product returned San Diego California

Great Call Splash is sold in Walmart, Target, other stores, on line and by phone contact. I purchased a wrist devise to notify in case of an emergency as I am elderly, living alone.  I was promised the monthly fee would be waived for the first month.  Not true, this bad faith company took the money out of my account in a nano second .  They also took $89.80 for the service devise and handling fees.   It did arrive and then would not activate as the Great Call service is not operating in my area.  I had the Great Call Splash devise tech on phone and he said it never works in your area.   I was told by sales gal on phone that my area was covered when it was not, map provided on box and web page shows my area covered but the thing was no use to me as it did not work.  I immedietly put this thing back in the package and attached the return label, took it to a UPS store as instructed and sent it off over 2 weeks ago.  All my calls to Great Call regarding refund of my $89.80 have a rep telling me it was never received.  What a way to operate in bad faith, assume if an elderly person purchases this non operating crap that they will fork over $89.80 and not expect it to be returned.  I wish I could find more sites to give this rip off company that targets the elderly more unfavorable publicitiy.  I would have never bought this devise had I looked at ripoffreports to see how many people have already complained about no service from the company after you've parted with your money.  Now I have to contact my bank and make sure these scammers do not continue to deduct from me.  Great Call is Great Crap, as well as  Great Call Scam and then owe me my refund.
