It is always the case that with these reports it is hard to demonstrate that the service provider botted on the account. Here though, we have not one, but two people accusing you of botting on their account when you offered services by hand. Both those people received bans for macroing. Both those bans occurred at around the same time. Both those bans occurred shortly after you provided the service. I think we all know what happened here - the only hand training that went on here was starting the bot.
IMO you should be permanently banned for that - at a minimum TwC'd.
As for what compensation should be awarded, I'd say you need to refund all the monies paid to you for the service, because but for the assurance of hand-training, they arguably would not have used your services. Furthermore, like
@Superfluous said, you didn't provide the service performed. I also agree with
@Superfluous over the account valuations, and would only add that although technically a blackmark against ones offence history is something that could be compensated, it is probably to difficult to value objectively.
As to the ToS issue, you represented that the services were done by hand. This was an essential part of the agreement. You cannot exclude liability via your ToS for a breach of this essential term.
Just to add an extra opinion here.
