I was wondering how I could block someone from my mail account because this guy [email protected] is from rcu and he kept buging me about some radios....that I made a offer on...and he kept asking me to buy HIS radios...he kept insisting that his radios were the best radio on the market....BS....I offered him $95 and he starts saying ****...like yea right I wont even give you one servo for that price...And so I made up something like how my uncle owns a hobby shop...so i could go to him for radios....that was a lie but just to shut him up......anyway he keeps on contacting me an keeps saying hes going to contact you guys about me....what should I do...?
