Horrible service. Account not updated

I lodged a complaint about my November payment not reflecting on my statement. I was requested to submit a bank statement as proof that the payment was made. After 2 weeks of sending my bank statement to Cathrine Pillay, I received no response despite promises of feedback. Two ago I received an email from Shaista apologising for the delay and she assured me that the issue has been escalated with the payment allocation team. Two weeks later, today I receive a statement which still does not show my November payment. No feedback yet. I call again today and I am told they are still waiting for feedback. Such horrible service.
