Mahopac Septic

Mahopac Septic DBA: Wind River Enviro/Earth Care
Pumped out our 1,000 gal septic on 12/27/19, and billed me $491.35
They subsequently notified me that ther will be an additional $108.57,
which they Unauthorized Took out of my *** Bank account.
On 2/1/2020, my septic is now gurgling through my shower, indicating
my septic is full again after only 5/6 weeks. We are only 2 adults in
the household.I tried to resolve this with Jake ,
He wants Us to pay an additional $795 for a seek and ***.
Clearly, this establishment is NOT practicing GOOD Business
