Horrible experience with a brand new fridge

I bought a brand new Frost free 298l refrigderator on the 25th of February 2021, which was delivered on the same day and we were very excited. 2 days later, the water dispenser started leaking and we reported the matter to the retail outlet we bought the fridge from who logged a call with Hisense to send a technician to look at it. Technician came and just assumed that it wa the tank which was leaking, after i explained that the dispenser is leaking from the outside. He ordered the tank and came and installed it, the fridge still continued to leak and i called him to tell him that the fridge is still leaking. He came and had a look at it again, and said that he will order a seal and come to replace it. the following day, i received an sms stating that the problem has been resolved, while the fridge water dispenser is still leaking.
