Pathetic service from Call Centre & staff

I want to buy an iPod touch 64 gb. I visited several stores in Pretoria and in Johannesburg. i phoned the call centre to help me locate the iPod touch (any colour). Your service is pathetic to say the least. The call centre tells me it is not been relased (after I told them it can be a fourth generation),whilst I bought one from them in December 2014! How can something not be released if I have bought one for my daughter. I asked for a 4th generation, not even a 5th generation. I can't even put my name on a waiting list, apperently there is NO waiting list. ***? Being in the media industry, and an Apple user, this is unacceptable. I spent 36K on a new Mac this month, I buy from iStores on a monthly basis. but after this I will make sure that everybody knows how bad you treat loyal clients. Samsung treated me better when I switched over to Apple. I have doctors Friends, that have lots of patients, and I already drew up a document to put as banner in their rooms for all patients to see how pathetic iStores and Apple is. Mark my words, you will lose clients (and lots of clients) because I WILL make sure of it! Get some brains, look after loyal customers!!!
