Springfield TV Repair

The next day, (Tuesday) I hadn't heard anything so I called in the morning (I admit I was jumping the gun a bit) and got an answering machine. This was at around 10 o'clock. I left a message saying I was anxious to hear the estimate and to please call me. By late afternoon I had not heard back so I called again and was told that they were having trouble reaching the manufacturer for a price on a part. That they had faxed the information but hadn't heard back (faxed?) I was told I would get a call just as soon as they heard something. I thought this was fishy (faxing for info - why not call or email?) But there are a lot of manufacturers so I didn't think too much about it.
I hadn't heard back by Thursday so I called again, this time around 9 AM. Got the answering machine again. Left another message. And again, by late afternoon, I had not received a call back so I called again. Still told they had not been able to get in touch with the manufacturer and that I would be called as soon as they knew something.
The following Monday morning I called again. This time about 9 AM. Got the answering machine. No call back. When I finally reached someone around noon, I was told still didn't have an estimate ready but that the smaller TV did not have replacement parts available and I said never mind. I was not going to pursue a repair and could I come and pick them up. And I also mentioned at that time how I had left several messages and never received calls back. The lady said, "Yeah, I haven't figured out how to retrieve messages yet. It's a new system."
My wife picked them up and when she did, there was finally an estimate written, but it was vague: "Damage due to power surge - Estimate $472 - $550". There was not a specific problem listed (i.e., what component went out and exactly how much it would cost.)
Essentially, I paid $105 to find out what I already knew ("Damage due to power surge") and then the estimate of repairs was only general in nature; not specifically stating the problem and the cost to repair that problem. I was also not contacted as promised and in order to find out anything about my service, I had to make repeated calls to the company.
I should also mention that the company was based out of someone's house in a residential area. Not that this should be an indication of unprofessional-ism; there are many companies operated from a home. But in this case, I think it only added to the overall unprofessional treatment I received.
