GET QUOTES - a bill I had not expected

I had a problem with my garage door - not closing properly, looked on internet of things, found provider, emailed asking if they could help, got a snappy reply.<br> <br> Technician arrived - took literally 5 minutes with allen key to adjust, tested - all good. I had asked for a backup remote but forgot to tell them the model. They went off to get one, programmed it, another less than 5 mins to program. I must say when I got the bill, I felt R 1134.30 was pretty steep, and told them that in no uncertain terms.<br> <br> What happened then totally defies 'customer service'. I have received two follow-up emails, and apparently been handed to their attorneys for complaining about the cost and not appreciating they are well trained, competent, and honest? <br> <br> My suggestion - GET QUOTES! The last person I used did a great job but has since retired. Two years ago, to PURCHASE and INSTALL and get 2 new remotes for the garage door was cheaper than this fixing and providing a backup remote (which on investigation now I hear is a pretty common and popular remote device)
