Unhappy Discovery customer

I would actually give them a zero rating. I requested a tax certificate .The main member was my mother. She was a pensioner and was financially dependent on me. I paid for the medical aid. I was authorized to act on behalf of this policy. All changes were made by me. The medical aid contributions went off my bank account She passed away I notified the medical aid. I am now requesting a tax certificate or a letter from Discovery confirming I paid for the medical aid (For the tax season). Discovery is refusing to provide me with this information as they require an estate letter/Letter of authority. There is no executor/estate. My mother was a pensioner that lived with me. There are no assets in her name. I was the premium payer, and the money went off my bank account. I do not understand why they can’t provide me this information. I am not making any changes, merely requesting proof that payment went off my bank account.

This information can also be sent to the same email address that was always on system. This is my personal information, and the medical aid was still active at this time But they are still refusing to send me the information.
