H&N Landscape

OK this is kinda a long story but you should listen anyway!
So I set an appointment for an estimate. AMBER comes to my house On a Wednesday takes measurements and tells me how much it will cost. Tells us they could be completely done by the following Wednesday. Then leaves.
After discussing with my husband we decide to accept the offer. I gave AMBER a call to let her know we want to get started right away, she tells me she is going to draw up the design plans and send it over email and when I approve her design we’ll write up the contract.
I wait and wait no email, so Thursday morning I call her and email her cause I’m anxious, I want the plans, I want to get the ball rolling. NO REPLY, until late Friday afternoon, she apologizes and says she’s sending the plans right over… OK.
Well I wait and wait again. Saturday morning I Send her and email and phone message saying, lets get this done so I don’t have to go elsewhere and that I don’t appreciate her flakiness etc…
Saturday night at 6:45 pm she calls me (no mention of my emails or messages) Saying that she’s been out of reception area all day and that she sent the email the other day and asks to verify my email addy just in case W/​E! Then assures me I will have that design plan in my in-​box first thing in the morning.
NEVER HAPPENED!
I’m about to spend $ 5 grand and I can’t even get a call back or the design plan… As their website boasts Customer service is their # 1 priority BS!
Monday morning I call the office and go off on the lady telling her all about my frustration and all she can say is she’ll take my number and have management get in touch.
No callback from management, instead a half-​assed apology email from AMBER with her chicken scratch of a design plan! She didn’t even have the decency to call me.
ZERO Stars!!!
