A-1 Sheer Gardening and Landscaping Verbally threatening non-negotiable company renton, Washington

I had hired A-1 sheer gardening and landscaping to trim shrubs, weed, deadhead hydrangea, raking and hauling of material. Once the job was done I was called and told the final price.I stated to Dolly Cheema that my husband and I were not satisfied with the work done on the back yard of the property. Trimming wasn't finished (boxwood on the front of the property and other shrubs on the hillside of the backside of the property). The hydrangeas were cut back extremely and Gurdip Cheema was told to only deadhead the largest hydrangea. Some weeding was also left undone. When Dolly Cheema was told this she put Gurdip on the phone. I preceeded to tell him the same thing and he got aggresive saying "the plants will grow back and that the boxwoods weren't in the price quote. With this aggresiveness my husband and I decided we didn't want this company to come back to our property. When we tried to renegotiate a price for the work done (front yard was done to satisfaction) Dolly got verbally threatening and harassing. She said "there is no room for negotiation" and expexcted to be paid in full regardless of the damage to plants that had been done and also work not finished. She also told me she was going to write letters to my manager and CEO of my job and let them know what type of an employee they have. I was told GOD would punish me for what I am doing. Dolly also told me that she has been in the landscaping business for 20 years and she knows how to destroy people. I was called EVIL. "It's EVIL people like me who try to get services for free by saying that a branch is broken" a quote from Dolly. Not once during my conversation with Dolly did I ever say that they didn't deserve some kind of compensation, just not the full amount quoted. Dolly was yelling at me for most of the phone call that eventually I asked for the company mailing address to be able to mail out some sort of monetary compensation. I hired another landscaping company that came out and finished the job with comlete satisfaction. The aggresive nature of both Gurdip Cheema and Dolly Cheema is uncalled for. All that my husband and I had asked for was just a renegotiation in price. People like this should not be allowed to treat customers the way they did. It's shamefull.
