Worst Customer service -Are our cars safe with this company

Worst Customer service ever, i have phone this company several time because they saying i owe 1 month. i said to them do the recon and find out how is ther an amount outstanding on my account. other will drop a call without assisting me, other will promise to call with the information, other will promise to email the recon with the full information and nothing get sent. i asked to be escalated to the manager or team leader they refused to do that. and then i gave up. now they still sending me the message that i am one month behind. i have escalated the matter 3 times till today no manager has given me a call to fix this. all they want is the subscription but not resolving the issue at hand. the employees from customers service until accounts are so ***********. they don't listen or take notes they respond with wrong information. i have dealt with more than 4 different peopl that were this bad so it painted this picture of incompetency beacuse not one or two but more people with bad service. it makes me wonder how safe my car if this company higer people like this and not teach them the telephone etiquette or customer service.
