Unbelievable service, sorry no service🤬

Wow Netstar, we bought a new vehicle in December and asked you to replace the unit that was installed in our old vehicle and that it was urgent because we are going to Mozambique. You did not want us to bring the vehicle in and assured us that a technician will install the unit before Sunday. Today is July the 6th and no system installed yet, just a letter of demand from nudebt. You can't expect to pay for a service that was not rendered. I will be in contact with the ombudsman regarding this and you incompatant staff at your call centre. After this mornings call they tell us that the system is still activated in the previous vehicle. Wonder what the response will be from the new owner if we activate it now. We need Management to contact us not your pathetic call centre. I am sure I will get a better response from the grade 1 class in any school. Please get in contact. It is terrable to see a company with such a bad reputation.
