Frio Service

I hope to never have to deal with attitude like his again!
So my large floral cooler has been struggling to keep at 40 degrees as the weather gets hotter, so since his sticker was on the fridge door I decided to call here instead of just talking to the previous owner of my shop.
To begin with he was not the nicest guy and in fact he seemed to be having a bad day as soon as he walked in my shop but I paid it no mind and told him my issue. He inspected the cooler and said that My cooler was installed incorrectly and that it would take 4 hours to correct the issue that he can see, but then said that he is not sure if this was the problem. I called the owner to ask if he has been told that before and the owner said it was installed 20 years ago and has only had one issue which was minor and he fixed it over a year ago so if it was installed incorrectly it would not be working for the past 20 years!
I explained that to this guy and told him that I have been here for 9 months and have not had any issues other then now, it’s not as cold as it should be. He then said that there was something loose that he can tighten, but that would take 30 minutes and that might be the problem but he was not positive. So when I asked him, OK well how much will that cost me? he gave me a big attitude and got upset because I would not «believe him» as he puts it and I would not hire him to do a 4 hour job that may not even be the problem and he wouldn’t even give me a price for the 30 min job to tighten something. Instead he stated I don’t want this job and he grabbed his tools and just walked away. This was an ugly experience and it felt that if he wasn’t going to make enough money then it wasn’t worth his time! I have a business and I know how important it is for us owners to treat people with respect no matter how big or small the job is. I have a second guy from another company coming out to check it and if he says its a minor thing or a big issue then I will let you all know the outcome but either way he should be more patient and more respectful when explaining what his findings were.
