Lemon Leaf

I posted an ad online. This nice couple responded. A Canadian lady and a British man. They met me at my property and handed me a nice business card and an add of theirs. I chose them because the guy said he was an expert in flower placement. They asked me for money up front because they put a very competitive quote in. I said I was uncomfortable with that but I agreed to pay the nursery directly and pay them $500.00 upfront.
They were supposed to start right away and It would take a day and a half to finish.
SUDDENLY. The guy's mother died, they had a family emergency, calls were not being answered, messages were not being returned. A few months later I called on a blocked number and when I mentioned my name the British guy hung up on me.
