HP Laptop

I Purchased a new HP laptop on 22/07/2021 from Hi Fi Corp Witbank. On the 28th of October I had to return the unit as it malfunctioned. I got it back on the 29th of November. (Note the timeframe). The first time I used it after the repairs was done, it did exactly the same. I returned it again on the 3rd of December requesting that I am not happy with the unit and requested to either have my money refunded or to have it replaced with a different make/model. Please note that Mr Mndeni Hlatswayo (Branch Manager) confirmed that it could have been a batch issue, and said that I must give him one week to sort the issue. I specifically requested that I DO NOT want the unit repaired again as I paid for a new unit and its about to be repaired for the 2nd time within 3 months. I just received a notification from JD service center with reference number HF ***, and as mentioned above, this is NOT what I requested from them. Please assist accordingly. I am trying to get in contact with Mr Hlatswayo without any luck. Laptop Detail- Make - HP Serial number - CND 1083KBZ
