Appalling Customer Service

I opened and account with my mum's contact number because I lost my phone. When I went to the gateway branch the assistant said it would be okay .. when I reached out to the customer service team because the account was held due to not getting through to me. The WhatsApp chat advisor was absolutely rude. Lungile just ended the session without answering my further questions to my query. Then I got a call from another advisor Darshen who said the account application would be declined because I used my mum's number.. they don't know what's going on in the service department. So by declining the application my credit score would drop and that's because of them giving wrong information. Appalling service shame.
