FRIDGE REPAIR

I bought a Russel Hobbs Fridge from Lewis Stores and have already paid R23,800 on it. Our fridge broke and on 8 October Lewis sent people from TV Centre to fetch it. They brought it back on 16 October. On 5 Nov we had the same problem and TV centre picked it up again on 7 Nov and brought it back on 17 Nov. 3 days later it broke again. We went to Lewis and the Manager said that TV Centre should put in a report to Lewis Head Office telling them that the fridge is irreparable. On 27 Nov TV Centre fetched the fridge again. Yesterday when I went to pay my account at Lewis I asked them what was going on. Tebogo then phoned TV Centre and they said they did put in a report and that they should phone Ashla at the Lewis Head Office. Ashla said that we must wait for them to see what they can do about the fridge and that we would not get a new one. We really NEED a fridge. What must we do if they say it can only be repaired February next year? Must we wait forever? We have been without a fridge for almost two months. Please help us!!
