EDGARS SOSHANGUVE CROSING

i have been trying to call Edgars in soshanguve crossing since Sunday, they do not pic up, i call their head office they say they can not assist me because i do not have an account with them and i want t buy a sneaker cash, i call the center management at soshanguve crossing they confirmed the number, but i don't understand why they are not answering their phone
