Upgrade of contract

2 weeks ago I received a call from Cell C about 2 weeks ago advising me that I am due for an upgrade. I told the lady to hold but she never called back. So I'm Friday 27th I called to find out about my upgrade and I was very specific informing Nonthando that I have been a loyal customer of Cell C for over 10 years now. Despite many colleagues and friends advising me to move to a competitor I always stayed and extended my contract. Despite all your ads to buy other customers out of their contracts, your service to your current loyal customers is pathetic. I humbly requested from Nonthando that I wanted an iPhone 6s 64gig and very decent monthly price. But I was told I could get the 6s 16gig on talk 200 for R549 but if I wanted a 64gig it would be R100 more. What I don't understand is that why loyalty isn't taken into account to accommodate the needs of the customer. Discretion can be app**** to keep the customer. For the first time in 10 years I will have to move to another network
