Appaling service and worst customer servive ever

My name is Jacky. On the 19th of January 2021. I bought a Hisense fridge cash at House and Home in East Rand Mall. It was only delivered later that night and upon delivery, I noticed that something was missing and could not stand properly. One wheel is missing. The following day I called the person that was assisting me, her name is Thabisile. She asked me to send an email to a person by the name of Dumsane which I did. They said someone from Hisense will come, it's exactly 3months later and nothing has happened.

Every time I call, sadly Thabisile is always surprised that nothing has been done yet. On the 5th of March, I went to the shop in person to find out what seems to be the problem. Thabisile was but Dumsane was there and seemed surprised that nothing had happened. What I fail to understand though is how come they don’t bother to make a follow up to check if this has been addressed? Instead of always acting surprised, that is poor service to say the list. The was no acknowledgement of the problem or apology whatsoever. He spoke to someone else and they kept asking me questions. I was later told that my surname was spelt incorrectly, hence the delay. About three weeks ago (28th March 2021), a lady by the name of Fiona called and asked if someone came and I told her that no one had come, she said she will call me back and nothing happened. I have to say this is the most appalling service I have ever received considering that I paid cash. Is this because cash sales do not have enough interest to make money for the store? Can I please have a refund then so that I can go and buy a fridge at a store that has the customer’s interest at heart? They should only contact me when they are telling me when are they fetching their fridge and to give me my money.

Regards, Jacky
