Frustrated is an understatement

First they do debit orders on the 7th when there is little money in the account. Then I ask on email for banking details numerous times. Got email feedback that's extremely vague and this morning they try and take the debit order again without even an email the day before saying this is going to happen. So once again it did not go through. What's going on Discovery... Where is your call centre people phoning? Checking in. Where is the people replying back on email with proper information as requested??? Are they not trained anymore?
