Customer service took a toll for the worst.

I've never had issues with Identity before this, they have always been so good, great customer service, but that all changed. Before the end of October, I loaded a debit order for my account payments to go off automatically, take note how I have never missed a payment in my 6 years of being an account holder. According to them, the debit order was never authorized, I did make sure everything was right on my end so it must have been an error on their side because my debit order never went off at the end of October. Now, even after I had authorized another debit order to take the full outstanding amount end of November, they are HOUNDING me with spam calls and messages, even after I had asked them to stop spamming me, I am literally receiving 10 calls a day, some even as late as 7:30 at night!? Receiving numerous sms's every day, my phone is blowing up and this is starting to interfere with my work. I have done my part to make the arrangements and they are still spamming me. This is ridiculous!
