The Discovery rot continues

Used to be a loyal Discovery client with multiple products. The service from Discovery has just become so terrible, "we don't give a dam" attitude and incompetence when they actually do react to queries. Over charged me in Feb (no refund yet) as they never updated policy as requested via email which they confirmed. More emails to get this changed. Cancelled policy with confirmation received on 16 Feb. Today I get debited. Call discovery, put on hold by retentions for 7 minutes and they then put the phone down. All emails are forwarded to a dedicated mystery agent with no assistance. No concern that debit orders will now bounce because of their incompetence. Sad to see a once great company lose its proud status.
