But the woman defended her prices and called out the woman for her harmful views.
"Holy sh*t $450 for some import to run a dusty cloth over surfaces and then push a vac[uum] around the place," the customer started her complaint.
She added sarcastically: "I'm in the wrong business. Assume an 8 hour day – thats [sic] almost $60 per hour for unskilled work – you're dreaming right.
"Wont [sic] be using your services thats [sic] for sure."
But the cleaning boss didn't take the angry message lying down.
She fired back a response of her own.
"Thank you for your thoughts, we are in fact Australian not that there is anything wrong with being an 'import' as you say," the cleaning entrepreneur said.
"A full bond clean is far more than a simple dust and vacuum, it includes the deep cleaning of hard to reach places, wall cleaning, the removal of mould, hard-baked dirt, the light fixtures, window tracks, in and outdoor windows, deep clean of the oven and this is just the basics.
"It takes far longer than you'd expect and is hard, non-stop work, however we are glad you will not be using our services, as we prefer not to service racist individuals."
The businesswoman soon took to social media to share her reply, unsure if she had been too harsh on the customer.
However, she was soon lauded as a hero by Facebook users.
"Me and my husband recently started a business doing bond cleaning, and I'm literally shocked at this response from someone," she wrote.
"I'm not sure if I've started something or should have responded better?
"Very few people have been unhappy with our prices, and I know many people have different priorities, some need the cheapest they can find … but, I feel her response was so uncalled for, and if that's all she thinks is involved in a bond clean, she could simply do it herself?!
"Maybe I could have educated her that we don't quote per hour, or that we have wages to pay & products & insurance to cover, or we could have chosen to ignore her."
Fans soon jumped in to assure her that her reply was pure gold.
"What a brilliant response!!! We had a cleaner a few years ago that did an end of lease or pre lease for our neighbour and she vowed that she would never, ever do it ever again! It was gruelling, so much harder and longer than they expected!" was one of the most popular comments.
"I think your response is perfect and I couldn't have worded it better myself!" said another. "I cannot believe the racism she tried to throw around."
"Whether or not it was a professional response, I say good on you for calling her out! And $450 is more than reasonable," added a third.
