poor service due to staff shortage

I bought a phone with telkom on the 7th of august. Its my fst time using telkom. Due to the fact that the shop is short staffed. They were only two in the store. The sales rep was trying to servealot of customers at once.in the end he did not give me information about my contact. Not even my paperwork. He didnt even explain to me how telkom works. So now I am stuck with a network that I dont even understand
