TrustedSite ‑ Trust Badges

At first the app was great, until i accidently picked the wrong plan and no I getting a outrageous charge even though I changed the plan once I realized it was the wrong plan. Then later deleted the app and the charge is still pending.

I think this is a scam app, it slows down the site, it tracks all customer info, after a year of using it I'm going to uninstall this today. how do I remove your app code?

Well, I see the potential for having this app on stores to ensure trust with our customers however, when I added it to my store it slowed my store down drastically. I decided to delete the app just to see if it really was this app that slowed it down and not something else all though it's the only app I've added in a while. A week or so later I was still receiving emails from them monitoring my website and letting me know how many customers were on my site at the time and how close I was to the 500 minimum for the free trial, AFTER I deleted them. I'm positive they're still on my store but just aren't sending anymore emails to make it look like they're not on there because of my reply to still receiving their emails. My speed score is still down and I pay another app service to keep the store loading fast. They've disabled my account preventing me from logging in again to reinstall which seems a little deceitful to be honest. I'm guessing because my store is still being tracked maybe?
I'm not sure if it's the company, a certain person(s) at the company, or the app itself that's the problem here. Please provide some feedback. thanks!
