Pathetic Customer Service

I spent R500 on Vodacom's new technology regarding screen protectors for two of my phones - on the first phone the screen protector is peeling off. On the 2nd phone which had a cracked screen - I was told that it would hold the screen together - the mic is now not working. Vodacom uses a liquid to glue the protector down - when I asked if it was safe to use on a cracked screen, I was told yes, until a day later when the mic stopped working. I took the phone back to the store where the managers, Alli and William, we rude, arrogant stating that we are trying to get something from vodacom insinuating that we wanted something for free. They then became aggressive and told us to leave and even called the security to remove us from the store. Please contact Michael Mavodze (security at Clearwater) on ********** . Is this the level of service we should expect from Vodacom, that when there is an issue and the managers dont know what to do, then they kick their customers out of the store? This is pathetic. I am going to investigate with Samsung, the liquid that they used on the phone!
