SHOCKING SERVICE!

I want to upgrade my contract to the blue topaz samsung galaxy s6. After finding out that none are available in Plettenberg Bay, I phoned the MTN in George (Garden Route Mall). I asked if they have the blue s6 in stock, the man I spoke to informed me that they had 2 in stock. I asked him to keep one aside for me, as I was travelling from Plettenberg Bay and wouldn't be able to come in immediately. Once I arrived at the store to get my blue s6 and upgrade, I was informed that they do not have any blue s6s in stock - only black and white - the man I spoke to on the phone said that the black s6 is the blue s6 (not sure how he came up with this logic!). I became irate as I had travelled 100km to upgrade, to find out that they cannot help me. The man was extremely rude to me, and couldn't tell me who to contact to order a blue topaz s6 - he informed me that not even Vodacom or Cell C can assist me. The service I have received from MTN has been shocking! Clearly, they do not want me as a customer - and Vodacom can order me this phone, so if MTN cannot assist me, I will be cancelling both my contracts and moving over to Vodacom!
