REPLACED PHONE WITHOUT DATA BUNDLE, SCREEN COVER

On 8 Dec 15 I renewed a contract which included a 30 GB data bundle for 30 days. Also had a screen guard fitted in the shop. After few days we noticed that the internet/data did not work and phone behaved erratic. At the time MTN shipped it for repair and after some weeks indicated that the phone will be replaced. The phone was replaced after the 30 day period. By this time the promotional data bundle has expired and MTN did not replace the rather expensive screen guard. I was asked to query this with [Email Removed] They came back with a response on 28 Jan 2016 that the data bundle will be replaced (between 2 and 24 hours), but that the screen guard will not be replaced. Nothing happened and I queried this on 8 and 11 Feb. I then logged a complaint with MTN Complaints Team (15 Feb). The complaint was acknowledged, but still no response.<br> I do not understand why the screen guard and data bundle cannot be replaced as the problem was caused by a faulty, new instrument. The lack of response is very frustrating.
