faulty Vivoactive battery

I am a little disappointed in Garmin SA. I've only had Garmin watches since 2012, never had any issues. I got the best service from them when a previous watch had to have a strap replaced, quick service, replaced the whole unit even without issues or me expecting it. I've passed my previous watches on to my parents, still going strong after all these years. Bought a Vivoactive4 2yrs ago, sudden failure of battery (and I really look after my batteries, I never overcharge, never charge directly from the wall etc etc) Had to pay a R500 handling fee, after 3 weeks only they get back to me with a sorry, unit can't be fixed and the quote for a new 1. The quote was nearly R2000 more expensive than what I'll pay for it online 😔 When speaking to customer care (took a very long time for someone to finally pick up the phone) the response is just "sorry".
