Pathetic Service

Good day. On 28 December 2022, I emailed Standard Bank Insurance brokers advising them that my car's windscreen is cracked. I received an automated response with the case number ***5 on the same day. I followed up on 3 January 2023 no response. Again I followed up on 7 January, no response. Again I followed up on 13 Jan, no response.

What must I still do to get some response from someone at Standard Bank insurance brokers
