Poor after sales

Purchased a fridge from Makro which was on sale. Paid R5 6999, saving close to R1 500... Only to find out few months down the line that it had a defect.. Recieved the email below : Good day Mahomed, Kindly note that Hisense has issued a credit note, and you have 7–14 working days to process an exchange. The store has advised that the fridge you initially purchased has been discontinued. You may therefore choose one of the following options:

Select an alternative product (including a different brand),

Request a refund, or

Top up the credit note to purchase another fridge.

Please note that failure to take any of the above actions within the stipulated timeframe will result in the forfeiture of the credit note.

My credit is R5699, but there is no price of fridge available at the price thats just like the fridge I initially purchased. What's a point of a 2 year warranty if a fridge cannot be replaced. Obviously now I'm at a loss to fork out more money to top up to buy a new fridge. This is nonsense. The credit should have been the original as it was on a sale unless that's what the what fridge is worth?!
