No good customer service

I am considering closing my Tymebank account for 2 reasons. 1 - I made a faulty cash send payment and I did not have airtime to phone, and the in-app chat function does not work for some reason, so I sent a whatsapp and until now I did not receive a response. Customer service sucks - I lost money yesterday but hey it's not your money so you won't care. 2. The fact that you cannot reverse a debit order from your app. 3. There is not a physical bank to go to and discuss your issues.
