Yes, some bank customer service calls are recorded like mobile phone customer service calls. The purpose of recording is to verify the service quality of operators. Second, if the operator's explanation is wrong and causes losses to users, it can be verified who is at fault. Under normal circumstances, the recording is internal information of the bank and will not be released to the public. If you really need it, you can of course listen to it through a third party (court, police, etc.). Don't worry.
