Dadson and its General Manager, Nick Yager, are unethical. Their business model appears to be based on what they think they can get away with.
They have a standing pattern of claiming equipment has been "repaired" or "works properly" when equipment cannot launder or dry a normal load.
When you call in to request a refund, they tell you to wait a month and never send it. When you follow up, they say they sent it on XX date. A week later, when payment doesn't arrive, they say the sent it on YY date. The next week, they give another date.
Between these ever-changing mailing dates and the fact some reported dates are business holidays upon which they are closed for business, it is blatantly obvious they are lying.
Given the chance to come clean and do the honest thing, they prefer to compound the lie and claim they've sent multiple payments and accuse users of "using them as a source of income". Yet they refuse to document or show cancelled checks (that they never sent) when their bluff is called.
Mr. Yager's 'solution' is to tell users not to use laundromat facilities in their building.
Dadson is unresponsive to building Management, tells them to have owners call instead.
If you own a commercial or residential business that requires laundromat facilities, avoid Dadson Washer Service Inc at all costs. Do not, under any circumstances, trust Nick Yager.
If you are a resident in a building with Dadson equipment, don't expect any refund when their equipment accepts your coins but doesn't do its job. You will likely have to get building management involved.
My building manager ended up havving to reimburse me out of petty cash when it became clear Dadson had no intention of sending the refund they had promised and owed.
