I recently got the bill for the last heating as well as a/c maintenance I got from the local Heating as well as Air Conditioning dealer; I was pretty shocked to see it was as high as it was! So I ran to the PC, picked it up as well as called the local heating as well as cooling contractor to inquire about the bill as well as why it was higher than I expected, however after placing me on a brief hold, they came back as well as found that there was a computer error, however they said that they were going to issue me a new bill with the proper charge on it as well as I would not have to pay it until it arrived. This was good because I did not want to supply them my debit card over the PC. A few weeks later I got the new bill with the proper charge on it as well as I sent them a check paying them what I owed. It just goes to show you that computers are not the perfect solution to everything. The world seems to rely on nothing but computers now days as well as it is kind of alarming. As my bill ended up totally wrong, imagine would could happen if it something way more serious. This is why I believe in good outdated fashioned human communication with everything! Especially when it comes to billing! I own my own supplier as well as I do everything by hand just prefer the outdated days when it comes to anything having to do with money. The local heating as well as a/c contractor should start doing this too. That is my humble opinion.
