Very Unhappy Customer

Please be very careful purchasing online from Cash converters. I purchased a laptop in January and the screen started going black in March. I contacted the branch(Moralateo Park) I purchased it from as they offer a 6 month guarantee. They first told me that the laptop will be collected in the morning and that the technician would be waiting at the store to repair it and return it the same day, then they told me that the laptop may take overnight to get to them. Now they are unable to tell me how long the laptop will take to be repaired and as a self employed person I obviously need to work to earn money. Even though the branches are franchises I honestly think there should be a link between branches for repairs especially as we are able to purchase online. Not to mention how I was spoken to by the manager of the store. I asked for the owners number and she refused to give it me. Think twice before purchasing from them.
