broken

so i got my car fixed. and now it's broken. they said it was just the battery cables and that wasn't too expensive to get done. so i was pretty happy about that. and when i went to pay for it and pick up the keys yesterday i started it just to make sure and it started just fine. but when i went to pick it up today it wouldn't start. it's done something different every time it's not worked. so i have no idea what it could be now. they had tested the starter and alternator when they worked on it and said those were fine. but now it's just revving and not turning over. blah. so our plans of doing all our driving to get mom's car back home today will have to be moved to another day. i hope we have another day to do it. everyone tells me when these things happen that i need to get a new car. i know this. but i really can't afford one right now. and i guess that's what i've been saying for awhile. so maybe i should start saving now. after i get this next thing fixed that is. but that's what i always say...
