New Battery Installed/multi Point Inspection

Just had to have my 2006 Prius towed because of dead battery.Tried jumping it but still nothing.Had dealer install new battery $145 installation $42 towing bill $125 (had platinum warranty but wasn't any good do to the battery not being warranty item) They did a Multi-Port inspection(what ever that is I'm not sure) determined it was low voltage from the battery which caused the problem...no kidding...hope there right. Haven't had any problems yet. Going on a 1000 mile trip next week. Had the oil changed while they had it in the shop...Total bill came to $460.91 Sounds like allot of money to me for just a battery and oil change...Think I got riped off on the towing bill. Tried contacting customer service to check on the towing fee. They aren't taking calls right now do to the demand on the problems they are having. Just wondered if the price was fare,not much though I can do about it now.Still love my Prius, as long as I have no more major problems.
