Query: Worst Sony product

We have always stood behind Sony's quality and their products have lasted a long time, until now. After 3 months, the tracking on the VCR tapes would not work. First we blamed the tapes and discarded them. Upon trying the tapes in our other machines, they were fine. We removed/reinserted the tape as the manual suggested, but that didn't help. It started out that the tracking would not hold after about 3 hours, then 2 hours, now 1 hour. E-Mail to customer support has been futile. We keep being pointed to other sites. Why can't they do that for us? The cost of mailing the unit in for repair nearly pays for a new unit.
