Confirmation of cancellation of downgrade

Yesterday I downgraded my medical aid package on the website. However, what wasn’t mentioned during the downgrade process was that my gap cover increased from ~R400 to -R1,100 monthly. After the downgrade was complete, only then did I receive the mail and instantly phoned to undo this. Everyone was friendly and I was advised this reversal had been done & no downside would happen.

But could I please have this in writing rather than just a verbal confirmation? I’ve been burnt by other companies in the past. I was told an email would come through conforming - but the last mail received still mentions the downgrade is taking place. Please can I just get confirmation this was cancelled and everything remains as it always has?
