Benefits stopped while account is paid

On the 6th of July, my employer representative and I forwarded a letter to discovery about moving my account to the employer. On the 15th of July I discovered that the amount was not deducted and I called discovery to which they rep**** there was an error. I then paid the amount due via EFT myself. On the 30th of July the employer representative and and I called and corrected the error going forward from August and the amount was deducted from my payslip and paid to discovery. Today 7 September Discovery sends an email saying they stopped my benefits. I called and they are telling me they cannot confirm because they do not have access to the list of beneficiaries from my employer and I am still listed as a private client. The agent does not know how to resolve my problem and I should go to my employer. But how, when changes were made by you.
