No service,response or communication

I lodged a complaint online. Serisha Nagan (consultant:complaints onboarding) requested the information from me to enable them to resolve the matter. After that I received a service request no *** in which they confirmed a deadline for 22/09. Since then I still kept on following up with the branch with no success. I also emailed Serisha Nagan twice, both emails were ignored. I posted on the facebook page also without any success as my question who the \we"will be that will be in contact with me"
