because I complained before

I had a problem a while back where I was told I can't look at phones before buying them. I asked a while back for a tablet that they must please get me even the area manager that I phoned Willem Swanepoel and he said today that he can't find stock in Limpopo so I phoned a few branches and I got a few. So I arranged for one to come to this store then I went to our store to arrange that, to find we have stock??? So I took one while I was looking she asked me about 4 times am I sure its the one I want so yes I said then at the till she underlined on the slip things and made sure again that I won't bring it back, and made sure again that this is their rules so I said listen do you have problem with me because I complained the last time, no she said she is just making sure I understand now really how stupid do I look??? I am not a problem person. So what is the issue I phone the manager again few times before he actually spoke to me and said she is reacting to his instructions, now really if you have a problem with me tell me and I'll buy at a mother place and close my account!!! I have had enough. Head office must phone me.
