I was billed for parts and labor that came in double what it should have been, but I understand it was a difficult job. I paid the first portion in cash the day of. I had to wait until later that day to get the rest. I have the full payment before the business opened on a Tuesday. When I spoke to Mr. Dahl, he sent one of his workers to collect. He had no ID but gave me the amount and showed up at the right house. I paid him, asked for a receipt. Employee did not have one. I told the employee I was not impressed by the business practices of Dahl Mechanical, but that the plumber did excellent work. When I spoke to Mr. Dahl he accused me of berating his employee and refused to provide me with a detailed list of the charges or a receipt for payment received. He left me nasty and rude messages. I texted him back, explained what I had said that that his refusal to give me a bill or a receipt was unprofessional. His response, and I quote "If you want a bill sent you are going to pay for my bookkeepers time to do it. Then you will have your professional bill". In my text to him, I wrote that bill was paid in full (he said around 887 and rounded up) since I had paid that and had no proof of payment. Today I open my mail and there is an invoice for the work he did, no record of the payment received and had the audacity to bill me for "2% interest on balance of 30 days". Fortunately, I have kept a record of my texts from him so I can print them out and send it back with a copy of the bill. I will not recommend this business to anyone as his "cash payment" was meant to go undeclared so he could double bill me later. Work done Aug 30, final cash payment in full Sept 5. Invoice states Feb 18, 2020 which is incorrect as I have not dealt with the business since. read more
