So much for being loyal Cell C!

So, I`ve been a loyal Cell C customer for the last 12 years. I`m due for an upgrade and have been for the last 2 years or so. Anyways, I get a call from Cell C mentioning the upgrade and what \special\" I qualify for and if I would like to take the special. I mention that I`ve see that Cell C management are now paying R20 000.00 to buy out people belonging to other cell phone operators. My question is this, if Cell C is paying so much to get clients not belonging to them why don`t they do the same for already existing members who are due for an upgrade. I want to renew my existing contract but wanted the new IPhone 6S which costs less that R15 000.00 - Reward your existing clients who already belong to Cell C rather than those who don't - so much for being loyal eh Cell C!!"
