I recently had a small issue with the billing department of my local heating and air conditioning company. I had hired them to come out and repair my central heating and cooling unit and I then charged it on my debit card. And what happened from there was a few weeks later I came to find that they overcharged my debit card by almost one hundred and twenty bucks! I knew this was totally wrong as the price for the heating and air conditioning repair as well as the heating and air conditioning home services was not as expensive as what was charged to my debit card. So at this point I called my local heating and air conditioning company to inquire about what I found on my debit card charge. They went and put me on hold for about 14 minutes. Then when they finally came back they highly apologized to me about what had happened stating that it was a fault in their computer billing system. They were able to fix the charges right away and put the overcharged amount right back on my debit card where it belongs. I was very happy when they were able to do this as fast as they did. Usually with something else they give you that crap about 5 to 10 business days. But not the heating and air conditioning company! They had their mistake corrected right away and all in all it was like it never happened by the end of the whole thing. Not to mention they gave me a voucher for a free heat and a/c tune up.
