What a Disappointing Service

Last year February we purchased a fridge a Hi-Fi Corp in Wonderpark. December it started being hot instead of being cold. We went to Montana branch on the 16th December2015 for the exchange or repair of the fridge. The service was horrible, They made my husband to push the fridge from the parking to the shop when we got inside he struggled to get service at the end of the day he was sent back with the fridge to say they will send a technician to fix it at home. Till today it is almost a month no technicians came, no update on what is happening. it is almost a month now. Who lives the whole month without a fridge????? There was a point whereby they called and said maybe he should take the fridge to Wonderpark maybe they will be able to assist him. Please do me a favor, when advertising please say \ WE HAVE THE BEST PRICES BUT WE LACK SERVICE AND FOR EXCHANGE AND REFUNDS WE ARE DIFFICULT EVER
