Ignoring landline

I saw a sneaker at total sports sandton & it hit me that I didn't have enough money on me to purchase the sneaker & now I'm tying to call sandton total sports to check if they have a size in the sneaker before wasting my time going to the shop & not finding a size... It's been a week now that I've been trying to call them & the phone doesn't get picked up surely they don't have sales all day everyday to make them so busy to ignore the phone<br> <br> What's the point to have a landline if they not gonna answer it for customers???
