Never heard of it, but let's do some digging.
The tandhconsult.com domain was first registered in March 2019. That's not super recent, but also doesn't show a long history.
The site offers credit card chargeback assistance. Assisted chargebacks are possible, but many such sites are really just there to collect upfront fees.
Oddly, the site also offers a number of education classes. Not enough details are give, especially the prices. I also find it odd that their lowest level stock class covers IPOs. Yes, those can be profitable, but that's not the sort of thing a new stock trader should leap into.
The London address appears to be virtual, available for as little as 2.08 GPB per week:
There are over 12,000 Google hits for the Hungarian address if you leave 5th Floor out of it. That must be a BIG building to have so many things in it, unless it's another virtual address.
Virtual addresses are suspicious, but aren't a 100% guarantee of a problem. Time to dig a little deeper.
Let's see what the fee structure is.
"Basic" service wants 499 GPB plus 20%. So, if you deposited 1000 GPB via credit card, used these people to help you get it back, and got the full 1000, you would pay them 499 plus their success fee. You might have a lesser chance with a DIY chargeback, but you would get to keep the full amount if it worked. For all we know, they're "help" might be nothing more than a simple standard script of what to say to your bank.
They also have "Optimal" service - Starting at 1199 GBP plus 17% of the amount recovered, if any.
Premium - Starting at 2499 GBP, plus 17% of the amount recovered, if any.
Diamond - 9999 GBP, plus 10% of the amount recovered, if any. If you've already lost enough to consider paying a 10k fee, maybe you should get lawyer instead of a chargeback service.
It can help to get the assistance of a chargeback company, but the vast bulk of the fee should be based on success. These upfront fees all strike me as quite extreme.
But, let's keep digging.
Look at the 3 images tied to the testimonials. Do you think those are real clients? They aren't. Check these links to see those same faces elsewhere:

Don't delay checking the images. It would only take them a few minutes to change them when they see this post.
So, are you ready to give more of your hard earned cash to a company that uses fake images of clients and charges high fees for its claimed services?
