What happened to the good service?

I took my 3rd 735XT for repairs last Monday. I phoned on the Wednesday to follow up to be told it could take 4-8 working days. Today I phoned AGAIN to be told they had my email address incorrect. The guy told me the price to replace my watch. The quote is extremely vague and now when I try phone to get hold of a manager I have been on hold every time for at least 10 minutes. The service at Garmin used to be so good. Maybe it's now time to switch. It's gone really bad.
