Purchased a leveling boost on WoW classic for 65-80, including the extra amount for 'super express' speed (2-3 days) and revered factions. I did not receive any contact from Kingboost within 24 hours of purchase, so I reached out to them on Discord. Within a few hours, things were set up. However, they told me the booster would start at 8 AM the next day. They tried logging into my account at 2:30 AM, leading to multiple issues. 3 days later and my character is only level 73. Not only is this slower than every other boosting site's STANDARD service, but it's extremely far behind the 'super express' pace that was paid for. I noted this to the Discord contact at Kingsboost, who told me they found a new booster. However, at this point, I'd rather just play my account.
