Poor customer service

I reported a ***** case on my account with their ***** department on the 28th of December, they provided me with two reference number and told me to email a police case number. I opened a case at the police station and emailed the case number twice but since then there has been no response or communication from discovery bank, I am absolutely disappointed with the service and I thought they are the one bank that can be trusted and has the best customer service but I guess I was wrong. I will never recommend anyone to use discovery bank and I am also going to close my account with them.
