After processing 88 complaints and thousands of questions from consumers over the last year, Yuma's Better Business Bureau has released its list of the top five most complained about industries in Yuma County. Topping the list in 2013? Our television partner KYMATV has revealed it is office supply sales by deceptive telemarketers. The bottom line here is to always ask about the supplier they represent, and get everything in writing before placing an order. Another industry the Yuma Better Business Bureau is warning against is roofing contractors. They say to always be careful, and never pay for more than a third of the job up front. Car dealerships came in third, and routinely make these sort of lists. Oil change garages came in fourth on the list, followed by property management contractors.
