WHAT KIND OF **** IS THIS?

on the 24/10/2018 I received an email from Nikesh Jaimangal from the credit control department to advise that they have an offer that would help with my car installment, I took up their innovation group car maintenance plan which put my premuim higher, I was advised at the dealership that my plan was coming to an end so at this point im expecting my premium to go down. I rep**** to the email and provided correct details to be reached on and even tried the telephone number provided ********** 314, the line rings with no answer. I have send countless emails and still no reply. I later on received a statement on the 16/11/2018 advising that my payment will be now going up. I am not happy as I still can not reach anyone who can help me.
