Arrogant technicians and consultants

i have been going in to the Vodacom store at Nicolway mall about 3 times a day for the entire week , I cannot get any assistance with my Vodacom phone, the technician named Boitumelo just looks pass me and when I speak to her she tells me she is busy and i must come back after half an hour, she looks very irritated every time I return. On Saturday I go to see her and she tells me " i only deal with walk in customers" what is that suppose to mean when i also walked through the door with a Vodacom product. I then return on Sunday and as I walk in the store a lady named Nthabi does not greet me and the first thing i hear from her is " she's not hear " ,Nthabi also looks very irritated She questions me about my problem and I now end up in a new debut that comes to the solution that I need the no mannered technician Boitumelo, Nthabi tells me "you should have take a number and wait for assistance" , After 6 days of going to the store she is the first person to tell me this . When i ask for the manager she tells me that there is not one on duty. i tried call Vodacom , if you try calling Vodacom i wish you luck. 1 week complete no help please Hello peter help me
