im just changing over to wfp and have had all sorts of problems,the latest one being with my trolley system,once again i have had to call on brett walker to come and help me out.touch wood im up and running.these have (i think)only been teething problems,but brett and his wife have gone out there way to help and show me,how to get things sorted.the trolley system can be a bit frustrating if your left in the dark.hopefully now,i can put my ladders away.
