Poor Service

I logged a service request on Monday(23rd October) regarding my 65inch TV which just drops wifi connection. I received my email that someone will get in contact with me. I waited till Wednesday and gave them a call. As per the agent she has sent an email to the warranty department and they will contact me within 24 hours. It's Sunday and nobody has called me yet. We can not use our TV as the wifi just drops at anytime. The TV is still under warranty.
