No Response after booking in a repair

I purchased a brand new item (Item Code - ***5) on 04 May 2021 at Cash Crusaders Bel-Air. On 13 June 2021, the item stopped working. I took the item to the store on 14 June 2021. The item was booked in for a repair. I phoned the store yesterday (21 June 2021), asking for feedback, the person who did not give me her name on the phone, said there was no feedback and that the owner of the store handles repairs and is not there today.

So, I have purchased a brand new item that broke after just over a month, the store takes the item for seven days and has no feedback? Has the item been just sitting there for 7 days? Has the item even been booked in for a repair?

The store then advised that they don't know when I will receive my item and I should phone back tomorrow. Why should I keep calling the store for feedback, when this is their job? Furthermore, how does a brand new item stop working in just over a month?

I have sent an email to *** on 21 June 2021. I have received a response, asking for my cellphone number. I did respond, but never received a response thereafter

It's now been 8 days and I have still not received a response.
