Airline Disregards Health of Diabetics

I recently had a very negative experience flying from Atlanta to Cape Town. On a 15 hour flight, there was no inflight food or beverage service for 12 hours, and my entertainment console did not work for the most part. Anyway, after returning home to Cape Town, I submitted an online Feedback Form whereby I lodged my complaint. Almost 4 weeks later, I finally received a response, which to say the least, was disappointing and a and low-value response. A paltry offer of $75 was offered and the case closed, so I challenged this the following day, by writing to Delta's Executive Customer Care Team.They gave now showed their willingness to try and retain my loyalty as a Sky Miles Member by increasing the settlement amount, which I appreciate. However, a few dollars more just won't do it. If they indeed want to retain my loyalty as a frequent flyer, and compensate me accordingly, they should be making a fair offer for the inconvenience and trouble caused before, and during the entire flight.
