poor customer service lack of feedback-totally useless

I called Tracker on the 28th November to inform that my tracking device is damaged , I was advised that I will get another one through a courier company and the amount for the replacement will be debited on my next debit order. the 2 days went by and nothing happened ...Like no sense of urgency, customer retention /service none whatsoever . I called again on the 11th of december and was given a lame apology and the same promise was given to me-courier will get in touch with me in 48 hours . I don't know if it's ignorance or not having any form of respect for your customers or just plain poor service . It's now busy times and festive season , if anything happens to my car will tracker assit me i higly dount and lost faith in them as s business and would never ever refer anyone to them if they fail to do something as easy as a replacement what lame excuse will they give me when if I loose my car yet they never ever forget to debit my account, so deliver that replacement without an extra charge as it's not my role as your customer to remind you how to retain your customer or cancel my account with immediate effect since you dismally fail to provide service
