LifeWatch Lifewatch Inc. Personal Emergency Response Systems Beware this company Lauderhill, Florida

In June,2006,my mother signed a contract with Lifewatch and paid the required up front fees, including a refundable $100 deposit. On August 16,2011, we shipped all the equipment to the Lynbrook,New York office as instructed by customer service. On August 22nd, I spoke to Jasmine in customer service and was told a refund would take 4-6 weeks. On Sept. 9th, Maria in cust.service said it takes 6-8 weeks. On Oct.15th, Jasmine said she will take it up with Paule, the billing supervisor. Is it a fair practice to hold back the refund of a senior citizen (96 years old) and also not to prorate the quarterly fee which was paid in advance. this company will take advantage of the elderly unless there is someone to keep after this company. Maybe they need the $100 more than my mother does. I have read on this site of another complaint of similar nature so this must be their practice, and perhaps elderly customers don't even remember that a deposit refund should be issued. Is that how this company makes their money??
