Valuing loyal customers

I am highly upset with my current service provider as I have been with them for more than 10 years spending on average about 5K a month with about 8 contracts on my account. I recently did upgrades for 5 lines using their upgrade department and I asked what freebees would be gifted to us since I am loyal to Vodacom and my spend is quiet high for an average consumer and the fact that wireless earphones, TV's etc were being given at store level to which the response was that there we no gifts since I was contacting their upgrades department directly and not going into stores (which is besides the point in my opinion as it is still Vodacom afterall). I since found out that one of my colleagues just recently received his 70 inch television from Samsung through Vodacom and this is highly upsetting since his spend is probably a 10th of mine. I would like someone to explain this to me as I feel ********** at the moment and am not happy with Vodacom at all knowing that 2 years is not a long time to wait in order to cancel all my contracts and move over to a service provider who values my kind of loyalty.
