Horrible service from Game Stellenbosch and Shareefa

So we bought a laptop from Game last week that was on a special, we asked the lady who helped us if we should buy office and she said no, it's already inside of the box. We went back yesterday for assistance as we could not find any office in the box and the office shows it will expire in a day. We waited to be helped, eventually one lady came very polite and says she will come and help us now cos she just busy with a customer so we waited. Eventually we tell her the story and she called for assistance from a lady called Shareefa. We explained the whole story and this lady had a attitude and telling me that it's not true about the office, yet on the laptop box is written big that the office is inside. She then walked away with our slip telling us she will be back. We waited and waited for her feedback which I don't know where she went to go and find. Eventually we got someone to call her over the intercom and she still took forever. We then decided to leave and eventually she rocks up with no explanation or office. We took the slip and paid for our other purchase at the till and left. Shareefa didn't event bother to give us any information regarding the office. I honestly do not recommend anyone buying a laptop from game stellenbosch or asking for manager assistance from this lady cos she is rude and very disrespectful towards the customers. Now what do I do in this case.
