Bad Retention Service

I requested to cancel my tracker subscription of which I've been a client for over 10 years. I received the worse service ever from Victoria in the retentions department, tracker will lose alot of business due to agents like her. She didn't listen to my request, wasn't focused at the task at hand, laughing while on the call, constantly repeating herself, talked over me, rude, unprofessional and have no clue of what Retention is about. She promised to process my cancellation and to send a cancellation letter which I never received. She put the call on mute and not on hold for 5 min to process the cancellation. She does not belong on the phones as she has no telephone etiquette.
