Ours included the free battery too. The picture up top is the misleading bit - that and the fact that when you ask the agent in the store, they tell you you're getting that model.
You need to mention the CPA to them.
Ask to lay a complaint with the store manager or owner.
Approach the ombudsman or ICASA
and
Most importantly keep your pic and maybe a video as proof. This is a national problem. Every telkom store will have the same issue.
You have to report it to the Advertising Standards of South Africa!
Dont settle with what you were given and make a noise. We unfortunately have to make a noise to receive satisfactory service. They misled you and dont allow them to do it to somebody else.
Edit : try to get a copy of the store brochure, make sure the booklet doesnt have a mention of the memory, scan and send with your ASA complaint. This will prove that they continue to mislead customers.
