Good service over the years......but

I've had an MTN contract for about 14 years (two actually) mainly because MTN has given me good service over all these years. Granted there has been one or two small issues in all this time but the good overshadows those to the point it doesn't matter. I have turned a number of people over to MTN (mostly family) because I honestly feel that the good from this provider is worth it. The only thing I wonder is loyalty for many years something that should/could be rewarded? I realize that contracts are an agreement of payment for service and that basically all requirements are met. Is it greedy of me to think that all the possibly of hundreds of thousands (my contracts have always been of the higher end ones) of Rands spent could be shared back by some small \Thank you"Token? I\""ve had friends gifted phones when threatening to leave their providers in the past. I'm in no way inclined to leave now. I was just wondering if maybe that \""Thank you\"" in some way is beyond some companies ability to work. But from my end"
