Hmmm, I thought the tow was probably part of the $1400, then transmission serviced, plus tracking down a shorted out wire which can take quite a bit of time. You probably were not really over charged for the shop charges. If there was a legitimate reason you couldn't communicate with Good Sam they may reimburse you for the tow. They did that for me when I was towed to a place that failed to fix the problem and then the same problem occurred and I had to be towed again. They arranged the second tow but would not pay for it because it was a "recurring problem". I appealed on the grounds that they originally towed me to a place that did not fix the problem and they reimbursed me for the $300 tow charge after I got home. I was very satisfied with the out come.
