Bad service

I bought a hisense fridge from OK zevenwatch mall in March 2019. This year, 2020 in July, I went to report that the fridge has a problem. A lady by the name of Nicole or Nicky assisted me. She made a call out to hisense and they came to my house to check the fridge. They told me that there’s something that is frozen from behind the fridge and they can’t fix it, so I must go back to the store and inform them. I went back to Nicky and told her that, she then told me that hisense said they had fixed the fridge whereas they have not. I told her that they did not fix the fridge they said they cannot fix it, she then told me that she will speak to them again and get back to me. Up until today, 4/9/2020, Nicky has not yet contacted me and my fridge is still leaking and I’ve had this fridge for only one year.
