Disgusting Service!!!

I'm actually disgusted by the service I received and words can't expressed how I really feel. I sent an email on the 4th of July 2023 to cancel one of my vehicles. I then received a call from a Precious on the 20th who had informed me that they received my email and a confirmation email will sent to me. On the cancellation request it stated that my request was received on the 18th which is incorrect as I sent it on the 4th July. I then called customer care and spoke to Nicole and informed her of this, she requested she needs to speak to her manager to confirm something if I can hold. She put me on hold for an hour without coming back to me. I then called back and guess who picked up the phone...Nicole again I was so livid, no professionalism nothing excuses of this and that. I requested to speak to her manage she then put me through to Samantha the cancellation manager I told her what I went through and requested an apology letter from Nicole's manager. I'm still waiting. She promised that she will sort the matter out and promised that I will not be debited for the vehicle and contact me I'm still waiting. To make things worse the debit order went off my account including the vehicle I cancelled. Poor customer service on another level!!!!
