Really poor customer experience

I have a joint bond with my sister through standard bank, we were granted a payment holiday from august until October. At the end of September we called and was told that the august refund will be done in 5-6 working days, then after 6 days there was nothing. We called again and was told that the first consultant didn’t log it, then we ended up calling numerous times with no joy and different stories. I am now tired of complaining and have logged this with the consumer protection act, I will also be blasting this all over social media so that this reaches the CEO of standard bank.
