I have been waiting for over a week to get my heating oil delivered, which I paid for over a week ago.
I was told last week that it would be delivered that day, and it was not.
Then the weekend came, and they re closed, so no delivery, although the heat must stay in, especially with the snow and ice storm we got.
Monday, Tuesday and Wednesday, I was unable to reach them by phone. - I simply hung on for over 20 minutes each of the 3 times I called, until I finally hung up.
I finally reached them today, and understand Bob will be making a delivery some time today.
How friendly after all of this anticipation and fright for my health and property to know that Bob is on his way, supposedly.
I now have a serious quarrel with Quarles.
I am not at all satisfied. I feel my trust has been abused, and it may not be recoverable.
