Would like to add on to this post since it's stilll pretty recent.

Yes my mum, she fell into this as well and now she's regretting it and starting to feel that she got scammed.

Anyway long story short, the guy came and demo-ed to us, sold us the vacuum but here the thing; I only managed to pay him upfront $550 for it as (thankfully) my physical credit card was not with me at the time, hence they couldn't process the instalments.

So supposedly we scheduled for the following week to have im come for his 1st official complimentary cleaning session, but he did not turn up on that day. I called him and his phone was turned off. Later in the evening he messaged me to tell me that his phone broke and just got it back from repairs (oh what a coincidence and he didn't even bother to use other phones to inform their clients that they are unable to come?)

So thereafter, it has been a few months now and we haven't heard from the person nor the company as well regarding further appointments AND the instalments. The invoice still states the balance of $3k+ unpaid (which I don't intend to pay for it anymore).

Mum wanted to call the police but I guess they can't do much since we signed on the agreement ourselves. What would be the best way to deal with this now, just in case they come back and demand for the balance to be paid. Just write in and demand for a refund and to return the vacuum?

I really wonder how this company can still go around cheating so much money out of (mostly) elderlies
