Tymebank may be anohter ***** enterprize

I have recently opened a Tyme Bank account and I was skeptical to start off. Now I am even more skeptical. I paid a small amount of a R100 over from my ABSA account to the Tyme bank account. It took a day to reflect. When I tried testing it by paying the money back into my ABSA account, It failed a few times with the OTP just not getting to my phone. Eventually the otp came and now the web application tells me I do not have any funds, even though it still shows my balance is R100. I do understand any new services go through teething pains, but what if this was my salary in that account and it tells me Insufficient funds? I cannot risk it and after reading reports from others with similar issues, Tyme bank sounds very *****.
