Bad Attitude Cellphone Consultant

On the 9th Feb I went to purchase a cellphone at exact vangate mall after standing for at least a half an hour before I was assisted by someone who could not complete my sale as it was not her till, she asked one of the other cashier's to help her, this is after I had to wait for a half an hour to be helped even though the shop was not full staff were busy cracking jokes instead of assisting customers,once I was assisted I enqired from the cashier how there out of box faliure policy works if no sim card is being issued with my headset she then said she is not sure and referred me to the cellphone consult a guy by the name of ***mie and I asked the same question I asked the previous lady and I was rudely told by him that tfg only has a contract with the cellphone company not service providers who provides sim,I proceeded to ask how can your policy work effectively if there is no sim card provided with the headset as if I go to any other store including a tfg outlet I will get a sim card with my headset and I was again rudely told it doesn't work like that at that particular exact store in vangate mall,I couldn't understand when the policy changed as I bought a cellphone 6 months earlier and received a sim card with my headset,I politely said thank you for your help to the consultant and left the store and upon leaving the store I overheard the cellphone consult speaking to his college advising that I am stupid woman who knows nothing about cellphone policies,I found this very insulting to say the as a person who works for a major cellphone company this was an insult,but as a loyal customer to this tfg outlet for over 10 years I felt very offended as this is not how customers should be treated,I am that customers are not always right but the should be a level of respect shown, especially if your customer is enquiring about things that is important when purchasing a headset,I am disgusted to say the least by this behavior.
