Extremely disappointed with Del Rentals. Have been renting a condo for 3 years with them, paying rent always on time, taking great care of the property. Contacted Del Rentals two months and a half ago for an issue with a microwave and rangehood not working. Genesis sent me a technician to check. Apparently microwave is too old to be fixed, so I was promised it will be replaced. Two months and a half later going back and forward, sending emails, calling Genesis and Osa, nothing is done. Extremely unprofessional property management.
