Customer service

Bee waiting for them to assist me with the banking app hence I'm in China. In WhatsApp they told me I will get help this week 14/12 to18/12 they didnt tell me which day or time or who will help me. I must just wait for help. Mind you I asked them to help me since last week. Twitter too it's the same story even on facebook messager worse they dont even reply to their emails. I provide them with all the details hey need but still no help. When I return back to South Africa I'm closing the account. Customer service is bad
