I'd say call them back & remind them that it's 110 degrees outside & it's going to be on them if you die of heatstroke...not to mention any pets you may have. Tell them if they don't get someone out there TODAY you're going to call someone else, then do it if they don't get you any satisfaction. Tell them you can't be on their beck & call having to take off work, that you can't just take off work day after day expecting the repair just for it not to happen...Good luck.
