Abysmal TomTom support

I had a TomTom runner 2. After about 18 months the watch stopped working - dead. This was reported to TomTom support and the promptly followed up and provided a replacement. At that point their service was excellent.

Unfortunately, the replacement watch died in exactly the same manner as the first after about two weeks. I again contacted their support and was told that a new watch would be delivered. Then I was told that they were out of stock, but new stock was coming. This started on the 22 March 2018.I still do not have a replacement, and any attempt to contact them through their support portal on the website results in a deafening silence.

I cannot find a contact number to phone someone, and have run out of ideas. I keep emailing them, but there is no reply.

So from a very good first experience of their support, it has now turned abysmal.
