I saw an offer on Paddy Power website 'Place a minimum stake £20 bet on any market on the Arsenal vs Leicester game and get a free £10 in play bet' So I put £20 on Sanchez to score anytime at i think around 13/8 and then at 0-0 i places Arsenal -1 (£5 free bet 1) can't remember the odds for that & put correct score 2-1 at around 8 or 9/1. The Sanchez bet lost and the -1 free bet lost but the second free bet came in. At the time though i had by accident used my own £5 on the 2-1 score bet that meant in reality I lost a £5 free bet as it was exclusive to that game! The total I won from the 2-1 score bet was around £37. The next day I had a message from Paddy Power to inform me I am now banned from any free bets, money back specials and basically all promotions. They did however refund me 2 x £5 free bets but no more after that for i guess forever! No explanation was given as per the T & C's they wern't obliged to and just said it was a business decision! Can anyone hazard a guess? it's not exactly breaking the bank £37!! Compared to what they have taken from me over the last few years!
