Warranty not honored after 6 months

I bought a Tacx heartrate monitor from Cycle lab at the end of July 2019. Tacx products carries a warranty of up to 2 years. At the end of November the monitor stopped working and on the 3 Dec I took it back to Cycle Lab Fourways who would send it to Garmin to check. I had to follow up today 12 Dec only to be told that Garmin will not take responsibility dor the repairs as the purchase was not made in their time. The consultsnt at Cycle lab told me that he can ask for a discount on a new monitor and I had to pay in the difference. I find it unprofesional that Garmin now owners of the Brand dont want to honor the warranty or that O now need to spend more money on a new product that is still under warranty. I was also told that Cycle lab can try and get the old unit back from Garmin.... I will never buy a Tacx product again as this is not the 1st time that I have problems.
