Tayna are well known for their fast and reliable service when it comes to supplying batteries, but also have a reputation for not honouring warranties and other issues fairly. I've used Tayna dozens of times over the years, for car, van, truck, stairlifts, fire alarms, disabled scooters etc. It had never been an issue for me until recently when I had a 4 year warranty Exide battery fail after less than 3 years. I just got the run around for two weeks and then nothing. I had to buy a replacement from Halfords when my battery should still have been covered and replaced under warranty. Having bought dozens of batteries from Tayna over the years, I wouldn't use them again and wouldn't recommend them. It's ironic that the guy who' the worse of the lot at customer service actually prides himself on it on LinkedIn.
