Massage was good but they irritated me!

So yesterday I went for a deep tissue massage.
I injured myself at the gym maybe over a year ago, I knew that weights weren't for me, my body felt heavy and I just didn't feel like me.
So when I injured myself I knew straight away that I needed to stop going!

I think I bought into the Instagram fitness crap.

Anyways prior to this I used to run and swim and use resistance bands I looked good and had no issues.

Long story short I've had neck middle back and extreme shoulder pain that has been restricting my mobility.

This massage did the business. I've not felt this good since before the injury.

But I was upset because I paid using an app with a discount. Which came with a discount.
Anyways after the treatment they cancelled it on the app then recharged me.
He didn't show me the fee, because he said that the payment hadn't gone through so assumed same amount. It was only when I got back that they removed the discount and added a £3 charge.

I've reported them to the company but I'm really pissed they did that!
