Ac and heating repair service near Chatsworth, CA

took my girlfriend's motor home here for a carburetor rebuild and general tune-up. was told it would be done within the week. 5 months later the work still was not done. we gave up and just had the thing towed away and sold it. while it turned out extra work might need doing (like the gas tank maybe needing replacement) we never found out- the only thing that ever got done was that the carburetor was removed. she had payed the owner, Mike- $500 in advance, to encourage him to actually get something done- and it did not help. he told us he would refund the money. then changed his mind and decided he would keep $100 of it for services rendered- which consisted of removing the carburetor. after no less than 8 trips back to this place over the course of 2 months, which were necessary because he never answered his phone nor returned calls- we got back a total of $300. I personally had to go because he refused to return her money to her directly, stating her bad attitude as his reason for this. it comes down to that he kept $200 of her money - for removing a carburetor. he gave reasons for this, such as that "it was too late to return the re-build kit" but it is not her fault he waited too long to do it. we both totally did our best to work with him, and he basically stole her money
