Finally cancelled with Tsohost after a number of years (almost a decade) due to the recent migration which they described as an 'upgrade'. Their service has been deteriorating slowly over the years with constant server downtime and email outages - the final straw was that they decided to put my prices up over 300% per annum for inferior service whilst also removing access to features like Let's Encrypt so that I would be forced to pay them an extortionate amount each year for their SSL certificates. This is now a terrible company that doesn't care about customers at all and which has cost me a lot of business because of their poor quality. I moved everything over to Skystra yesterday (they do free migrations and it was incredibly quick with no downtime). Will not be looking back.
