Unhappy customer

I was at the vodacom in 3 simmonds street and they advised that they dont have the Samsung A5 in stock, I should go to the Glen. I have went to the Glen, the didnt have and they have call the Vodacom in Southgate mall, with the specific contract I want and availiability, Southgate advised there do have stock. I went to southgate mall vodacom on the 9th August 2015 and they gave me the phone with the package that I required. Zanele advised me that I will recieve the selfie stick on the 11th August as they dont have stock. To date they did not call me as advised to notify me if i should come to collect. I went there on the 12th August and they stil dont have stock. This morning 14th August, Vodacom has debited my account with the montly payment, but i still do not have what I have signed up for (selfie stick). Is vodacom just pushing sales? When will I recieve the stick? Can they not call me and notify me of the issues they expirencing with deliveries? I am a customer, but not being treated as one. They are quick to take my money, but not provide what was on the contract.
