You might take a look at EffluxTV. They have a 3 day trial period. I’ve had their service for about 3 months and am very pleased. The EPG is very easy to navigate and user friendly. They have a nice VOD selection, including new releases such as Avenger Infinity War, Baby Driver, etc. I get the major US channels - ABC, CBS, NBC, FOX, CNN, TBS and a few others as well as most of the cable type channels I got before with my satellite service. It also includes premium channels HBO, Showtime,Starz, Cinemax and some Canadian stations that have some good programming. Not too sure about all of the sports you mentioned but I did watch a preseason NFL game on NFL Network a couple of days ago.
I don’t know anything about the details of the support service you mentioned. but the customer service is great so you could contact them directly - the few times I sent them a message I had a reply with 2 hours at the most, usually much sooner than that.
