Poor service from game

I purchased a brand new fridge from game at gateway mall on the 15 October 2018.On the 15 of November i noticed that all my food that was in the fridge were starting to go off because the fridge wasn't cooling,there were even ants in the fridge.I then called game and they asked me to bring the proof of purchase so that they can sort the problem out.I did so and a couple of days later a technician was sent to my house to check what is wrong with the fridge.He then informed us that we need to get a new fridge as this one was faulty.We then went to the store on the 26 November to inquire why haven't we received our new fridge.The lady by the name of Salo informed us that she has to apply for a credit from Hisense and only on their approval will they be able to issue us with a new fridge.From that day onwards I've been calling game every single day to check up on the progress of the credit application.With every call that i made i was assisted bya different person and on each occasion i had to explain my story from scratch.I will then be told by that sales person that they were not aware of this so they will call me back as they need time to find out what happened.When i asked to speak to Salo i will be told that she's not in.To cut a long story short i called the store on the 04 December after having to throw away yet more food that was off.I was very much upset by their lack of interest in my case and it was then that i was assured that the new frigde will be delived on the 05 December 2018.As expected the fridge wasn't delivered,I called in and asked to speak tothe manager and he re assured me that i will get my fridge on the 06 December 2018.It wasn't delivered so my husband and i went to the store and mind you we just emptied the fridge again as all that was in it went off.On our arrival at the store we were informed by Salo that our fridge isn't reflecting on their system.Today is the 08 December 2018 and after throwing away all my food yet again i haven't received a new fridge.Im experiencing emotional stress as i have small kids to feed and other bills to pay.The financial loss i have encountered from this is just too much and im very much disappointed by the kind of service I've received from this store.I need answers as i can't afford to buy anymore food.I don't think it even occurs to them how important the fridge is.
