FNB navCar service BIG fail

I completely dislike using social media as a platform for complaints but if you simply cannot get attention then I guess this is the only option. FNB, I have been using your navCar functionality for the last couple of years to renew my vehicle license without any hassles. This year though has been a different story. I made my payment on 20 July to ensure that I met the expiry date of 31 August. I had to pay a fine to get the license approved and did this on 13 August after I had to query why nothing was happening! The courier company then never bothered to call to check whether I was home and simply delivered it to my neighbour on 18 August. Much to my dismay, the disc was not for me, but for some other person who now probably has my license disc. I have been trying to get hold of someone at the navCar team ever since with no luck. Emails just simply don't get responded to, phones just ring, or they promise you "someone" will get back to you and even my personal banker (new and never met versus the star I had before) did not bother to assist. My license has now expired and because of the insurance risk, I cannot drive my own vehicle due to this situation. As an RMB Private Bank client, I am dismayed by this poor service and shocked as this is not the standard that I have been used to over the years. Please can someone get back to me that can actually make this happen??
