Business ProfileforCape Cod Oil Company

I called Cape Cod Oil in early November 2021 to request an oil delivery. I spoke with a lady in the ************** who informed me I had a credit of $349.59 from the previous season. They delivered my oil and mailed me the **** and my copy of the delivery ticket, ticket #***** which shows the delivery was ***** gallons at $3.29 per gallon for a total of $382.63 minus my credit on file of $349.59 and my total due being $33.04 which they were suppose to charge to my debit card they have on file. On Thursday, December 9, ************************************* the mail from Cape Cod Oil showing my balance due of $33.04 outstanding. I called to have that charged, as it should have been on delivery day. I spoke with a lady ****** who informed me I owed $542.00 not $33.04 and she asked permission to charge the full amount immediately to clear up my outstanding ****. I said absolutely not. I need proof and to understand how my **** went from $33.04 to $542.00 with not other purchases. On Friday, December 10, 2021 I received a telephone call from the Office Manager ***, who was quite abrasive and I could immediately tell had a chip on her shoulder as we started to speak. She snapped at me saying "oh you've never made a mistake before", and I said everyone makes mistakes but show me, explain to me, don't just demand over $500 more than I expected to pay. She then said "well if you are refusing to pay your **** I may just have to call Uncle ****** and tell him about this because he will be responsible to pay your **** as the owner of the property if you don't pay it" (I rent my house from my Uncle and being a small town she is aware. Sure enough, this nasty bully called my Uncle to tell him my business and our dispute. I have never been treated with so much disrespect. I simply want to be shown and to understand what money I truly owe so that I can get this matter cleared up. I am trying to resolve this problem, not be belittled, harassed, and bullied by ***.
