I feel really dumb now ^^; Thank you so much for your help

I know it is a silly question but I've gone thru my phone pie menu and can not find a way to contact garden club members. I have met two of them an old man downtown and the old woman who came to my home when I started.

I have tried inviting the old woman over she has no options for me to join I keep reading the manual that came with the game (useless really) and it says to call a rep for membership ... where do I find that option? Please help me ; ; I have two sims with gold gardening badges and am ready to try some friendly competition with other members of the club.

Thank you very much in advance

P.S I have removed all hacks from my game.
