Bad Customer service

I have a problem with my refrigerator and tv that I bought from Hi-Fi Corp Southgate Mall 2020 ,my freezer stopped working and my TV screen is blank. I went to the branch on the 2nd of March with my bankstatement that shows when I purchased the products because I didn't have my slip. When I got to the branch I was assisted by Joyce at customer service, she advised me that she will send an email to head office to request for the copy of my slip before she can assign technicians to come fix my refrigerator and tv. She then further informed me that she will call me either Sunday or Monday for feedback. I didn't get a call nor any feedback from her or the store. I took the liberty to call the branch to find out how far the process is, she then tells me she hasn't done anything 1and she won't be at work because her child is sickly however she will try to assist. Tuesday I call again, I am told she is not at work she will call me back as soon as she's back. Wednesday I call again they tell me she is out of the branch, I spoke to some lady on the phone she then advised me that at head office they requesting a reference number at the back of the fridge and tv and I asked why I wasn't informed the first day I came she couldn't answer me, she then told me Joyce will call me as soon as she gets back from lunch. She still doesn't get back to me, Thursday I call the branch again, no answer, the whole day. She then calls me on Friday to say she needs the Ref for the fridge, I explain to her that I have the Ref number and I have been trying to get a hold of her to no avail and I am at work Monday to Sat I can't make it to the branch, she then says it's hectic at work but she will send me a WhatsApp for me to send a picture of the reference number, she doesn't. I then went to the store on Saturday after knock off time, when I get there she tells she was busy and pilled up with work she forgot to attend to me again. She then gave me her WhatsApp number to send the pictures of the reference number, she will call me Sunday morning for feedback. She didn't call me on Sunday. I ended up calling the store again up to no avail, I ended up calling her cellphone to ask for feedback, she tells me they don't have electricity at the store and there's nothing I can do, if I have a problem I should contact her manager and drops the call. I am frustrated as my fridge is not operating, my house is smelling because of this to a point where there are worms coming out the back of the fridge. This is bad customer service and I feel I am not a priority as a consumer. I need feedback as soon as possible before I take this further. At this stage I feel like I am not valued as a customer, I have to spend my airtime calling the store and my petrol to go the store.
