Homesure

It took 50 minutes to reach a representative on the phone. as I tried to explain to the representative that I had my credit card statement and evidence that my money had been paid to the company and not returned to my credit card, the representative told me that it did not matter what my statement said and I would need to contact the credit card company to request my money back.

This company, whose parent company seems to change often, offers a home appliance warranty that is very misleading. The service is called "TotalProtect Gold" and costs $600/year. When service is needed there is a $75 co-pay and then some, or none, of the repair costs are covered. 
My microwave failed and they charged me $75.  It took almost 2 months to get the repair finished, and the crowning step was that the warranty did not cover the cost of the plastic bracket that held the replacement part in the microwave; they charged me another $31 for that. Two months later, when the microwave failed a second time (same circuit board) they refused to repair it. The original cost of the over-the-range unit was ~$1,000 and a new one is now $1,300. HMS offered to give me $311, or a cheap $270 unit that they would install. When I pointed out the fraudulent nature of the settlement (versus their advertising hype), they just pointed to the weasel-worded fine print and refused any discussion.
You are much better off putting the $600 in the bank and then shopping around for a reliable service provider when things fail.

HMS of The Mid-Atlantic States is another name for Homesure of Virginia, Inc, and they have accrued over one hundred Better Business Bureau complaints in the past 36 months, and thirty in the past twelve months. Another red flag was that the contractor assigned to the claim does not have a BBB report even though the BBB has requested a report. The myriad complaints about HMS on the web are worth reading.
