Poor service delivery

I ordered an iphone 5s from them 4 months ago i have phoned to enquire twice and still waiting for phone to arrive. I filled out a contract, if i wanted another iphone 6 i could have walked out with it that day, but i prefer the smaller size of 5s and understand there was a stock issue at the time and was told i would wait a maximum of two weeks for the phone to arrive. Telkom are still advertising the 5s on their website in january 2016 and i ordered the phone sometime in the beginning of October 2015, so how is it possible for people to not deliver any service or at least call or email to keep you up to date with a purchase you signed for? <br> <br> Telkom never gets back to you wether its online or ordering direct from a branch. In a sense im glad, imagine i had ported my number over to a company with such poor service delivery.
