Bad customer service!!!

I was called by someone from the accounts department at 7;34 am this morning telling me that my debit order has come back unsuccessful, I told her that is not possible as it reflects on my side that it was taken and successful and I had sufficient funds in my account,she was very rude she said I must go to my bank and check because it is definitely unpaid,i told her that it may be a problem on their side,however she was rude. I then checked my bank statement and it shows the debit order was taken on the 9 November 2019 also she told me a lower amount than what was debited. I then called back I was redirected 6 times to the control room each time they say they are putting me trough to the accounts department, the 5th time a lady tells me that the accounts department only opens at 8am, 8am you say but I received a call from your accounts department at 7:34am. Cartrack has the rudest consultants and I will be taking my business elsewhere ,id rather pay extra for better service!!!!
