First of all, I've been using this bot for 2 days now, and it's legit perfect. I don't mean it ticks everything perfectly because that's highly suspicious, but it plays just like I would play the game. Cuppa cooked with this and the fact that you can play directly from Runelite, rather than logging in through a shady website, is huge. HUGE.
I had an account banned with a separate company because they were using the legacy client, and it's weird when you are not using the system that everyone plays on. Blessed to have found Cuppa.
It definitely isn't intended to be paying 20c for one kc; It sounds like Runemate might have been crashing for you?
Unfortunately that was not within my control: Runemate was down a few days after the game update, which is uncommon, but it's been updated and everything should be working now. As well the transactions themselves are handled Runemate side: It charges on bot start & each hour after, so if a bot is crashing please feel free to test using the trial or try later, or DM me, to avoid being charged multiple times.
Either way, feel free to submit refunds via https://runemate.com/store/sessions, if you like.
