Allen & Sons, Allen & Sons Appliance Repair stole an item from the house, changed price from what was quoted Canoga Park California

This is a follow up in regards to my 10/27/08. After one week of the repair of the microwave, it again malfunctioned. I contacted Allen & Sons to come back. I scheduled an appointment and they called to confirm the appt two times the day prior. I called back to reconfirm. My husband waited at home all day and they never showed up. Turns out they left me a message on my cell phone at and b/c I didn't return their call to again reconfirm their appointment they just didn't show up. They claimed they dispatched someone to the area, but because no one called back they left the area. They didn't even knock on the door. If they did, they would have found that my husband was waiting at home all day long. I called back to spoke with the manger to request a refund. I spoke with a secretary who confirmed a refund would be issued to me within 2 weeks. They I received another call back from the manger to confirm this and he stated this was not true and that they can not refund my money. So after 4 visits, taking 4 days off work, we are out $135 and our microwave still does not work. This company goes by Allen & Sons Appliance Repair and has "offices" located all over the Greater Los Angeles Area, from Santa Barbara County down through Orange County. If you look up their addresses on a map, you will find that they are just P.O. Boxes (located in city after city). I have never worked with such an unprofessional company ever.
