Best Erosion Control in Portland OR

I used River City Environmental based on a recommendation and could not be more displeased with the service provided. I'm only giving 2 stars because the man who performed the service was kind. I was charged more than $500 to solely inspect a root problem; no actual work was done to help the issue. Then I was told the excavation team would be in touch. It has been 3 weeks and no one has bothered calling me - you can't even flush my toilet or use the laundry because of the overgrown roots - and today I received a charge to my credit card without even receiving an invoice. If you need a company that will respond and solve your issue quickly, go with OC drain. **UPDATE: The customer service team apologized and refunded part of the cost**
