Best Buy

On 2/5/19 we purchased a Samsung Refrigerator, Stove, Dishwasher and Microwave with a extended 5 year warranty understanding from the salesman any time in the 5 years anything that goes wrong they will repair or replace. Since purchase we had to exchange the dishwasher, have the refrigerator repaired twice, and the microwave twice. This last time regarding the microwave I called the 800 # and explained my problem and was scheduled for service on the 9th. The next day I was called by a repair co. to set a time. Reviewing with them I was told to re-contact BB. 1st call on hold for 45 min. then dis-connected. 2nd call 30min. on hold then dis-connected. Upon my return home in my emails I received notice that the microwave would not be repaired but replaced and go to the store. After going to the store we selected a replacement. Then was told by the mgr. we needed to purchase a new 5 year warranty as the one purchased on 2/5/19 is now expired because we had a claim. I do not understand 5 years means 5 years not 25 months? This is not what we were told at purchase, this is misrepresentation at best. If not Fraud. I would like a response ASAP and a good explanation. I just hope the store mgr. got it wrong.
