He is definitely a guy you want to deal with.
When I first contacted him for his well trained blood alt ( with 99 mining and crafting), he first made sure to repeat his ToS and had everything well explained.
Unfortunately I myself ran into an issue with the payment where I couldn't proceed for at least 2 days. He was then very kind and patient with me.
Once I had the amount of 200m OSRS gold paid, he immediately let me change the registration E-Mail and sent the login/registration information right after.
Communication throughout the process was flawless and as you would expect from a reputable business man.
Also the explanations to exclude any kind of misunderstandings - very professional.
5/5 in each possible choice.
