Vodacom pavilion

I recently upgraded my cellphone contract at Vodacom Pavilion and opted to getting a gear fit2pro at an additional cost per a month. The device had a software problem and needed to be sent in to be accessed. After giving them their time to get back to me I called in on a Tuesday to find out the progress. I was told that their advanced repair center was waiting for spares. On the Thursday I called back and was told that the unit is no longer under guarantee due to physical damage and they were quoting me R1800 to fix the damage. I was in shock as the device I had sent in was not physically damaged. It took Vodacom a week to get back to me and explain that the courier company has except responsibility for the damage. They have now repaired the damaged unit and expect me to be happy with the result. I feel that they damaged my watch and should in turn replace it and not refurbish the broken one. Tired of being treated like an idiot..... need to find out if this is against the consumer act as I do not believe that this is fair practice
