Liquid Capital Cutomer Care - more like No Customer Care

As an existing client, I called Liquid Capital *** to have an extended vehicle service plan added to my current vehicle service plan. The very helpful Ernst(my 1st initial contact) informed me that I need to pay an additional admin fee of R120 as the extended service plan is seen as a new product. I was then transferred to the not so friendly Bupile(Team Leader) that mentioned this admin fee is a business rule. The same was mentioned By Pearl from Customer Service My question is as follows: 1. I am already an existing client, so why should I as the consumer pay an extra "once off" admin fee? 2. With a premium of R479 per month over a 3 year period; totalling to R17244, Why is no-one willing to waiver the admin fee. Am I not important enough to keep as a Customer??? 3. If this is a Business rule, it does not make it Government law. I am totally shocked at the service that I received. I would advise all consumers to research companies before committing.
