i purchased a samsung refrigerator and i bought an extended warranty for repairs and service and I'm having trouble with it to day so who do I need to contact for repair?

Good answer. You might stop by Home Depot and see what their department that sold you it has to say or exchange if it's that new, sometimes they might do that to keep the customer satisfaction per si.

Call the number on warranty booklet they gave you

Good answers from all My niece has been with them for about 27 years in the large appliances and assures me that they are helpful. Jim
