Confused

Please explain to me Altech Netstar. I called in on the 7th April 2025, spoke to Kutlwano after the self help line did not help me. The reason for my call was to request moving my tracking unit from the old car to a new car as i am selling the old car. The contract is still new. Kutlwano told me i should phone back with the name of the contact person from the dealership where the new car is. I phoned back on the 8th with the name. I spoke to Bulelani and explained the reason for my call. Bulelani told me there is an amount of about R600 that i have to pay for re-installation of the unit on the new car. I explained that the day before i spoke to Kutlwano and he never mentioned anything about the payment. Bulelani told me that Kutlwano will sort that out with me as he never mentioned to me about the payment. I also need the installation certificate on the new car for insurance purposes.
