Harassed by Manager at Scarborough shop

This message is regarding the Scarborough Store and regarding the manager who threatened my partner over expressing an opinion. I've copied and pasted from MY facebook status. I WILL spread the word and make it CLEAR that guy needs some disciplinary action.

I am going to pursue every possible way to get you more training. Your customer service skills suck, I'm not a specialist but I'm sure that if a customer is looking through the products you sell and commenting on it being overpriced there's nothing you can do about it. It's a matter of opinion. You do NOT get into the customers face and threaten them.
Seriously, go re-evaluate yourself. You're in DESPERATE need of training.
What happened?
We were outside the shop with  Dog. so obviously couldn't go in store. We were waiting on a friend who was inside the shop. One guy looked at the window, he saw a housephone, nothing special. So basic, It may as well have been a cheap phone from Tesco. They were selling it at £35. He pointed out that they probably only bought it for a fiver. And the manager of approached him, stood right in his face, invading his personal space and threatened him. He called him an idiot and said " IF you don't leave now, you'll regret it" . He made a big scene so EVERYONE on the street could see what was going on.
Even the old woman walking past was horrified at the manager's behaviour. She said she'll be putting in a formal complaint. I hope she does.
I will be contacting your regional manager and I will HOPEFULLY get you to go for more training. Imagine if it had been someone else, imagine if it had been the old lady walking past that you started on and threatened. What would she have done? She'd have been scared!
Next time, if you come anywhere near me I'll be contacting the police. This is harassment and is COMPLETELY unneccessary.
