inboxdollars claims account inactive for 6 months Internet

i have been a member of inboxdollars since 2006. as far as getting any rewards close to their claims, well thats few and far between. i had recently noticed i had not received any emails from them for approximately 6 weeks. about an hour ago i got an email from them which said "welcome back"? never left so why did i get this email. i signed in and it tells me i had been inactive for 6 months. this was not true. so when i went to the help dept. now they are saying i'll have to wait for some other dept to contact me. how does 6 to 8 weeks turn into 6 months? i already had enough for another check from them. now they say i forfeited that by this bogus inactivity
