Faulty Fridge

Highly disappointed with service i have been receiving from this shop we bought a fridge last year July its only been a year and the fridge is not functioning properly - I contacted the customer service to report my issue as the fridge is still under warranty , a technician was sent he then advised the fridge ran out of gas but he has since refilled the gas , We were on out way to a holiday and we left immediately after the technician had advised that all will be in order with the fridge upon our return we we welcomed by a foul smell coming from the fridge - all the contents inside was spoiled to our surprise because the technician said the fridge was functioning properly - we contacted the service centre again the technician was sent to our place and he advised the fridge has an internal leaking??? why was this not picked up the first time the technician was despatched its only been a year and we already have problems with this fridge ??? Would definitely not recommend this company to anyone - If you want peace of mind and unspoiled food from your fridge then stay away from Hi-Fi Corp
