Hello and welcome to the forum. I separated your post from the OT thread since it's about WInd and Telfort, so here it's better.
AFAIK Telfort is not anymore an O2 subsidiary from quite a long time and it's not a member of the Starmap Alliance either, so it's impossible to use Telfort vouchers to refill a Wind card.
Anyway I suggest NEVER to direct dial 4242 since you pay 1eur/min to do that, while if you dial *124*4242# it's totally free of charge, which is much better in my opinion!
