I have had similar problems with different VPNs. Now I have solved the problem for good. I bought a Raspberry Pi (a small computer same size as a pack of cigarettes, for those who dont know). It is cheap - like 2000 Baht - and uses very little electricity - so it is turned on all the time. I made it into my own private VPN server. Not only is this VPN working perfectly, it is also using the same IP as the house that pays for TV subscriptions - as it is located at there. It would be impossible for the TV distributers to know anything.
Now you probably think you are going to be a computer expert to do this. Well, I know a little, but I have never worked with Raspberry/Linux before. I simply asked AI how to do this and that. It would come up with exact commandline instructions - step by step. I was very surprised I could get this working - but now it is.
I can explain more about software, if someone wants to give it a go!
