Elizabeth Braithwaite, You could try contacting the manufacturer(1st link below) to see how well they will stand behind their product(voice your concerns of problem) or enquire of their recommended service center in/near your location. You could try to do a search in yellow pages or on the Net for local repair shop, 2nd link below may help. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
