Account debited double

Poor service. Filled in all documents to remove myself from the membership and my spouses membership to continue as normal but i have still been debited for two memberships instead of one, apparently due to a system generated error. What i am surprised about is when i called discovery health on the 30th of June as a courtesy to make sure that everything is in order i was assured that the only debit will be for the one membership(spouses membership) from the 01st of July. I again called discovery health on the 01st of July to dispute this after noticing my bank account was debited for two memberships and i have recieved the following reference number ***. Please contact me so i can send all the email correspondence
