Poor customer service

I contacted plumb time on a Friday to request a plumber to fix a leak in my home. I spoke to Cheryl, who said a plumber would come the next morning. Saturday, I waited from 8am. Around 10:30 I called plumb time's landline - no answer. I smsed Cheryl asking for confirmation and an expected arrival time. No reply. Half hour later, I called Cade Smith (the boss) to explain the situation. He said he would find out what was going on. I did not hear back from him. At 11:15, I called another plumber and informed Cheryl and Cade not to bother coming anymore. At this point, I got a rather rude phone call from Cheryl asking why I was cancelling, and insisting that she sent me an sms saying the plumber would be there at 11:30. I gave in and cancelled with the new plumber. Then I got a call from Cade's plumber saying he's running late because he had a 10am appointment. Plumber arrived at 11:45, and mentioned that Cheryl was blaming him for everything. She should have told me on Friday to only expect someone after 11am. Her behaviour is rude & really unprofessional. I will not be using plumb time again, and will advise my body corporate to remove them from our complex service provider list.
