Hi Paul, and welcome back.
Sorry about the IT issues. I’m sure technology saves us all an awful lot of both time and money, but sometimes it’s very easy to think that life was a lot easier in the good old days! (Even if I’m pretty sure it wasn’t really …. it just so often seems that way.)
Fwiw, I’ve had no problems with either Betfair or Oddschecker for sometime now, although of course I only use Oddschecker for a few minutes each day (given that most bookies make me about as welcome as a bad case of piles!)
