MTN disappoints yet again

I decided to upgrade my phone via your site, this seemed fast and easy. DSV contacted me regarding the delivery, I explained that my thumb prints do not work with the bio-metrics, they advised that I contact MTN to make a note for manual delivery. I contacted MTN telephonically only to be told to hold on and then had to listen to the multiple prompts again and then a noisy background and nothing. Sent an email to the customer care. DSV has just been to deliver my upgrade which was not given to me as my thumb prints do not work! I am beyond angry, phoning MTN is like watching paint dry. I have been a client for many years and time and time again with your disappointing service I don't know why I bother. Fix you service, it's not service!
