Cant get my Acer repaired by Incredible Connection

On the 23rd December 2015 I took my Acer tablet into Incredible Connection Cresta to have the touch screen repaired. I was told to bring it back after Christmas as Acer were closed for the holidays. I returned on 4th Jan only to be told that only Rosebank Incredible Connection could fix the screen and I had to take it there. Rosebank told me they would fix it by the end of the week (8th). I traveled back to Rosebank (a 20 minute drive) only to be told that they were awaiting a part from Acer. I was told I would be called when the repair was done and it would only take a few days. On the 23rd January a full month later I called Incredible Connections Rosebank (who never called me back) only to be told it wasn't ready and the person who was fixing it was unavailable. I asked to speak to a manager only to be told they were busy with customers and nobody could help me. Eventually the manager phoned me back and told me I was too angry and I should watch my tone. At that point I realised that Incredible Connection do not really care about the material issues like repairing my tablet. I will go into Rosebank tomorrow, remove the tablet and then take this up with Acer directly.
