Discovery and Uber in a loop to undermine customers

When I write complaint earlier this week Discovery re Uber (which does not reply to a complaint) said it would reply to me. I was sent a a document to get the debit orders to Uber reversed. I filled it in then I receive a response asking for the same information I had already provided. To repeat when you go to the Uber application to deal with the debit order you get put in a loop that just goes round and round. Quite clearly the Bank does not read responses and simply sends out the same requests (also in a loop).
