While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more

DODGY. Should be illegal

DODGY.

I subscribed to his service in August 2023 after being approached by Jon Reineck (founder) and asked specifically to trial the product. I was told there was no free trial, but I would get my money back if I didn’t like it.

I’ve now discovered that my company was charged continuously for around three years, despite me having no evidence that we actively used the service during that period and receiving no renewal or service communications that I can find.

More concerningly, Support Sidekick shut down on 3 August 2026, but billing continued afterwards. The founder has confirmed this and refunded the two months covering the closure period plus one additional month, but has refused to refund the earlier charges, stating that the service was “live and processing your data throughout the subscription period.”

I asked for evidence that the service had actually been processing our data, or evidence of renewal/service emails during those years, but have not received any.

My complaint is therefore that we were left paying a recurring subscription for years without meaningful communication or apparent active use, and were even charged after the service itself had closed down.

They refused to do the honest thing and refund us, so I'm left leaving a complaint here and he'll keep $5000USD for fun
