License disk not delivered

I have paid my license disk on 30/09/2018 and I still did not receive anything.

I have to call and follow up and every time they tell me that delivery will be tomorrow. A month later and it is still not delivered.

they also confirmed my address 4 times and I have to speak to someone different every time.

I mailed Nav and called every day last week, and they promised it will be delivered the following days but it’s never been delivered.

I am getting no service from Nav, so I called FNB and the consultant advised he cannot give me any number to assist and they don't know who can help me.

I need a follow up please.

Someone that can just help, I have been getting the worst service and I can’t wait for my license disk another month. please.

A friend of mine had good service and what is different with me?

Kind Regards,
