Abhorring Customer Service

I had an abhorring customer experience at Ok Furniture Gezina Galleries. So on Saturday 10 December I bought a Haper and Muller 32inch TV Set after making the purchase I waited for a long time and the TV didn’t come, I then stepped out to the next door shop checkers to fetch a trolly to carry the TV , I returned and the TV was still not there I don’t know what was still happening but after a very long wait someone from the back brought the TV to me, I immediately noticed the careless way that he was holding the box with the TV inside such that the tip corner of the box was hitting the ground with every step he took. He opened the box tilted the TV and plugged it into the switch the light come on I didn’t have a full view of the TV as it was tilted, to me it seemed fine at that time considering that I saw the light on the screen on, However when I got home, unwrapped it and plugged it on I now had a full view of the screen and immediately noticed that the top corner was dripping ink all the way down it was already late for me to return it Saturday as the store was already closed the time I got home. I returned it the next day Sunday morning 11 December 2022, The manager David Miyeni immediately accused me of damaging the TV and twisted my words around when he spoke to the reginal manager over the phone which I requested to speak to the reginal manager and he denied I then requested the cell phone number that I might contact him myself instead he instructed the sales men to give me the head office contact details, it was Sunday and head office only works weekdays , I called the next Monday on 12 December and the lady referred me back to the same store manager David Miyeni whom accused me of causing the damage and twisted my words and didn’t help me at all, I requested the Cell contact details of the reginal manager and once again I was refused even at head office, I then requested an email address and that I was provided with I emailed same time and no response has been given to me yet. This is a typical bad customer experience I really regret going to buy that TV set at OK I didn’t only waste my petrol, Money , energy and time I was treated so bad and accused as a ******** while what I did was spend money to buy a TV I still don’t understand it and I am angry about this, As I write this the TV is at the store a, I don’t have the TV , I spend my money and now I have nothing. They didn’t exchange it , They didn’t give me back my money , they say they will take it to the supplier and get a quote that I will be responsible to settle if I want to get the TV fixed, this is crazy I am in shock and really I don’t really know what to do.
