Well done? It's not that there is no future, but the future is rather bleak, but if the salary is ok, you can do it first.
After all, if you enter that door, you can get in touch with the people there, and maybe you will be appreciated or something, but the chances are relatively small.
Customer service is a relatively low-level labor type, so you can learn some common sense such as bank savings, because you need to answer others, of course, you should know.
Secondly, although entering the counter is a chore, you need to master much more than customer service. Reconciliation can't be wrong. I am very busy every day and often work overtime because of reconciliation.
Above, investment, wealth management, loans and other departments are more comfortable.
Anyway, customer service is a very low-end job because there is no risk of touching money or customer accounts.
And you have to be qualified to enter the counter, not so casual, like an accounting certificate.
