It’s taking the motherfunking p!!!

I signed up to iPoints a while back in order to try and gain some cash back points on online purchases etc. There are some sign ups where you gain bonus points if you sign up to other sites eg bingo sites and the like! Today I signed up to I luv bingo - wagered £10, received £15 bonus funding and I have actually won two games - nothing major. A jackpot win of £20 and a shared jackpot win which meant I received £5 odd. I am trying to boost this to £30 so that I can withdraw the money and run before I blow it all. But alas the site is now teasing me by sticking and won’t let me access the “bingo hall”. There was me on a winning streak and nowhere to win!
Off to try again before the nursery run.
