Lack of knowledge experience and enthusiasm

Vocacom The Reds Mall the consultant did not have any knowledge on how to open the phone to insert the Sim card nor did she have the correct equipment... She wanted to use a normal paper clip then was afraid to break the phone what nonsense... She also could not advice me as to which type of Sim card should be purchased to use on a short term basis as I am here on holiday for a month from another country
