Careless and unprofessional

I took a burial policy in 2020 and I sent Rand Mutual Assurance documents from my previous insurance for them to waiver the waiting period.

I on Monday 29th August I called the company requesting them to send me the policy documents they sent me and I realized that instead of my sister they have captured somebody who I do not know with the same date of birth as that of my sister today I called the company and the receptionist by the name of Matshepo was very rude and dropped the call I later called and spoke to Lebohang and she put me through to Kotini and I requested him to transfer me to the manager and he said I should send an email to request to speak to the manager My sister has Said I should cancel her name from the insurance company because they were careless and unprofessional she said how could they do such a careless mistake of mixing up the names
