Is it really too much to ask?

I don't think anyone even reads my blog anymore so I am going to take this opportunity to RANT! Is it really too much to ask that service people treat you honestly and fairly? We recently replaced both our A/C units in our house with top of the line equipment. We spent a LOT of money on these units. Think 5 figures, nice new car-- now you are in the ballpark with me on how much money we spent!

We did not have to buy these units, we could have had the old one fixed (only one was having a problem) for about 1/10th of what the new ones cost us. But we liked the A/C company, we felt the guy was treating us fairly and we decided to bite the bullet and go ahead and replace both units.

Part of the reason we bought the more expensive units is because of the rebates being offered by the A/C company. They offered us enough back to make it worth it to wade off into this and buy the upgraded equipment! Yep, you guessed it.... now they don't want to pay and the guy is saying he never promised us the money. Even though we have it in writing. They want to give us substantially less than they promised us.

We have been fair with this company, always pay our bills. We have paid them a service fee every month for the last 3 or 4 years to have a service contract with them on our A/C units. They already have payment in full for these A/C units and are now lying to keep from giving us the rebates they promised us (in writing)

I feel like everytime I have a service person into my home I must be holding up a big sign that says....."Please take advantage of me, please overcharge me, please do a shody job, please call me a liar when I expect you to honor your agreements"
Even the companies that advertise they are "Christians" have done this to us!

We need to have our carpet replaced and some tile work done but I am so afraid of being taken advantage of that I don't want to have it done!
