terrible attitude by a consultant

I purchased a Vodafone tablet on 04/03/2015 on 11/04/2015 the tablet died I returned it, and they sent it for repairs I was told it will be in the store on 17/03/2014 Tuesday, I went Tuesday to check if it arrived, and it had not, on Wednesday and Thursday on Friday, I looked for the manager and a rude consultant by the name of Zola told me arrogantly that the she didn't know were the manager was, and **** to me that her colleague who had been helping me with follow up during the week was on leave, and that I was boring them in the store, I just want my phone and I am closing the account !!! after what that woman did !!!
