Case Manager Pheladi from Nissan ignoring my calls. Horrible customer service

My query remains unresolved and the case Manager Pheladi is ignoring my calls. Whenever o call, its either she is in the toilet , lunch or on another call. She is never available to speak to me.

I demand a written notification of my case and why it has not been resolved so i can escalate this matter to the ombudsman.

The treatment and service that i am receiving from Nissan is unacceptable. I have to constantly call and ask what is happening and clearly nothing is being done with this case.
