What am i doing wrong?, im mission 100 dollars to buy washer and dryer
There are two quests to earn money, they get you enough for both phone parts and the washing machine.
I always suggest to buy the washing machine first, since I am unsure about the script quality and how quests are connected.
I assume you have not finished the hospital quest yet. In that case you have to wait for the call.
HOWEVER, if that quest somehow depends on having bought the washing machine first ... then load an earlier savegame and spend your money wiser this time
