Rick Ross's troubles seem unending and is struggling with business relationships lately.After the Reebok dump a Florida tour booker says the rapper stiffed them, after working together for years.

Total Access Talent filed a lawsuit in a Miami federal court this week , saying Rick Ross Touring hired it to book and organize a month's worth of Florida dates starting last November,but never paid the 10% commission.

 Total Access says it's been booking Rick's tours since 2004 without incident. The lawsuit says they were so comfortable doing business cos the singer had never defaulted, and this made them arrange the tour with a verbal agreement.

But Total Access says this time, Ross' camp did an end-around after the company already set up opening acts, arranged dates, prepared contracts ... the works.

Total Access says Ross owes at least $171,000 in commissions.

Tough days for Rick , if only he could retract that date rape song, he stands to lose between $3 million and $5 million after Reebok ripped up his endorsement deal after his date-rape lyrics kicked up a storm.
