I've been with TSO host for years. They used to be very good but this all changed and their service is now dreadful since several years ago in my opinion.
There's no telephone support at all, live chat is not available often and your website can be down (which mine is regularly) for many hours before anyone looks at your support ticket.
Nobody takes any responsibility or ownership for you as a customer, and in my personal experience downtime is shockingly bad. I will be looking for a refund (again) which will inevitably be ignored and will take my custom elsewhere. I recommend to avoid TSO hosting at all costs as in my experience they are dreadfully bad.
