Cancel Swiss Life

Hello, a few years ago I unfortunately concluded an ETF retirement contract with Swiss Life through a “financial advisor”. The argument of avoiding/saving taxes in old age convinced me. I now understand that that probably wasn't the best idea. Now there is almost €13,000 there. I pay €280 a month into the ETF. Does it make sense to cancel it and just put everything in the MSCI World and just continue saving there? Or are there other reasons at Swisslife?
