Appalling service - Consumer Complaint for INCREDIBLE CONNECTION - HEAD OFFICE

This morning I went to Incredible Connection Tygervalley, Cape Town to have my ac adapter of my Dell laptop checked out and to buy a new one if necessary. So I asked a salesperson on the floor if they could possibly assist me and tell me if my charger could be faulty. He took the charger went over to a Dell laptop and plugged it in all while I was trying to explain to him what exactly happened and what message came on my laptop screen when this adapter was plugged in. He kept on dismissing me and just told me the adapter is fine and working. So I asked him to please explain to me why it does not charge my laptop nor my daughters new laptop, but he says it is fine. Once again I was just abruptly told, IT WORKS! So I told him it makes no sense and if he would listen to my story he would understand. He was not interested and did not listen to me one bit and just kept saying it works. So I asked to speak to a technician... upon which he replied, once again, in a rude tone, he will tell you the same thing! He just would not give me the time of day and should not be attending to people as he has no people skills and is downright rude! I then left the shop and went to Computer Mania where I was assisted by friendly staff members who listened and helped me sort out the issue. I did indeed need a new adapter and bought one from them. If your sales person took the time to hear me out and acted in a courteous manner I would have bought the adapter at Incredible Connection. I am appalled that staff get to treat customers like this and I would really like feedback on this matter. His name is Gidon or Gideon, he was mumbling so I couldn't hear properly. A response would be much appreciated, Thanks.
