Game's poor customer service

Good day

I was at Game Kimberley on Saturday and they couldn't assist me with an upgrade on my *** number. The Vodacom contract they've printed showed 2 black Y20's for R269 and their in store offers was for 2 blue Y20's. I was then told that they'll take it up with Game's head office. Yesterday i went to Game and was told that they haven't rep**** yet to their email and therefore i wasn't assist

I app**** online and was told that the contracts are not available for upgrading customer but for new customers only. The lady told me to take out a new contract, i told her that the brochure showed that the contracts is for new and upgrading customers.

My question is why would Game advertise contracts that aren't available to customers. Why isn't head office giving feedback regarding the query. If I can't be assisted online and in the store then where should I get help?
