Poor service

I went to Vodacom on the 3 Mar 2015 to take out a contract for a Tab. I was told there was no stock of the phone but agreed to wait. Its now been two weeks and I have had zero feedback. I even went to the store and left my number with a different salesperson because the initial guy wasn't available. Still no contact!!! I do understand how back orders work but surely the company has a responsibility to keep the client informed??? This phone was meant to be a birthday present for my son, which fell on 09.03.2015. I find service like this very lacklustre and unprofessional. My existing contract expires at the end of the year, I will definitely reconsider continuing my subscription with a company that takes customer relations so lightly. I am very disappointed
