I will never buy any electronic device from Pick 'n Pay Hyper again

I bought a Samsung microwave on 01 November 2020 at Pick n Pay Hyper Wonderpark branch. On 28 November 2020, I took the microwave back to the store because it was making a loud noise when in use.

To this day, 25 January 2021, I don't have the microwave back. I bought the microwave for R2 699.00, and I don't have a spare microwave. What on earth do they think I use in during this period?

The details of the microwave are as follows:

Samsung 55L Microwave (Black) Model number/Serial number: ME6194ST/XFA J62K7WRN800402

I initially thought the microwave was with Samsung for repairs, but Samsung can't locate the microwave using the serial number provided. Therefore, it appears that Pick 'n Pay took this microwave to a third party for repairs.
