Slacking Customer Service

I called 3 weeks ago and after holding for almost 30minutes I hung up on the call, totally slipping my mind I returned the call today to make the smallest amendment of my debit order date to prevent any penalties due to the fact that my salary date has been moved to the last day of the month.<br> <br> Holding again for 25 minutes and calling three times in a row just to get the calla answered, I get through to some sarcastic customer care consultant who refuses to help in anyway.<br> <br> I understand the 5 day notice but yesterday I could not get through to the call centre.<br> <br> Quick to take money but cant even consider one days grace.I have to wait until next month to even make the arrangement.<br> <br> I am a good customer and do not feel comfortable ever dealing with this call centre again.
