unable to puchase items

My name is Seth and I cant Buy items despite me having enough money. I am bleeding money to timer. why am I " unable to perform action " when I have plenty of money. It says I dont Have enough money to buy silver stock that costs 20000 and I have over 50000. I cant buy useable items either. this is very dissappointing since I love this game so much. I only play on the Iphone and will now consider not playing dispite purchasing the 2 $9.99 packs. please help

Thank you, Seth PS my pets name is "add-nyhrsus"
