Guru Muscle review for Zestard ‑ Easy Donation

Their customer service answers fast but on the other hand, I was facing a lot of issues with this app. I have paid my monthly subscription and the app has never worked properly. It made me more issues and bugs than something plus. When I told them to remove all code from my theme they left not even some lines of code but also a full snippet or template. It could be a great app but it seems to me they need better developers somewhere in their Dev office.
