I nearly blew my top when I gained the bill from the last HVAC system repair call I had. The price was supposed to be only a little over a single hundred dollars for the Heating and A/C labor that I had done. But the bill study almost 5 hundred dollars! I was not having this at all! Right away I went to the iPhone to call the local HVAC system corporation to demand to speak to someone in the billing department instantaneously. They were going to get an ear full from myself and others and also have myself and others tell them that I was not going to spend money the bill! When I finally got someone from billing at the HVAC system corporation on the iPhone, I told them everything that was wrong. They looked into it and found that I should not have even got that bill as it was meant for another client who had extensive heat and air conditioning system maintenance labor done. The other person then got my bill. There was a mix up… So, what is going to happen now is that the local HVAC system corporation is going to mail myself and others a correct bill. As for the other guy who thinks he may have gotten away with paying a little over a single hundred dollars for whatever he had done, well, he’s in for a not so good surprise! But that isn’t my complication now is it? That is for the local HVAC system corporation and their billing department to labor out on their own!
