Tymebank Theft???

I withdrew money from an online merchant that I was working with on the 09th of October 2021, which was said to take within 48hrs to reflect on my Tymebank. I waited...2 weeks after, I called the merchant, they said the withdrawal was successful on their side, I need to check with my bank, I called Tymebank, the lady who was helping me said there is no money. The merchant resent the money to my account, till date I still have not received any money on my account. I read complaints from others about Tymebank witholding people's monies without reason. Shouldn't we be alerted when they decide to withhold our monies? Im now having second thoughts about Tymebank.
