Yes mate, their CS asked me that right at the start.
Originally registered under yahoo and just changed to my hotmail one. (registered totally from scratch and CS closed down the yahoo account)
I was then blocked from registering due to my mobile number which flagged up on their system, told CS agent as I registered while on with them, asked to 'try again' a few seconds later and it worked!
Activation link came thru to hotmail no problems but CS also cut n pasted it for me and I was good to go.
Deposited there and then and FS 'coins' showed up but when games opened no FS were there so she added them manually to both games (Piggy n Starburst)
PS: @Lookaway do you know me from somewhere in 'real life' lol. Reason I ask is you called me by my nickname 'Jono' which I've never used on Casinomeister but mates n family use all the time, or just a case of spooky wooky lol
