Most pathetic service provider

My samsung not 4 that i had taken on contract from vodacom was blocked by them. When i went to the repair center in old fort rd i was told that the were no technicians that could help and that the device could be faulty coz it shows that there is nothing wrong on their side. I was then sent to samsung who checked the device and told me it was blocked. I then called vodacom an was transfered to over 5 different departments until eventually the figured that the device was blocked in error. I was transferred to the accounts were the lady who assisted me had no idea what she was even talkin about an finally apologised for the phone being blocked. She then tells me that it is now unblocked an should work. That never happened. I had to evetually go to the la lucia vodacom where i was assisted by a friend of mine an the phone was eventually unblocked. He also could not give me a straight answer as to why the phone had been blocked. All that was told to me was that it was an error. The phone was also reset and alot of my infomation ect was lost. I cannot believe the service an the staff of 1 of the biggest networks in south africa. Really upset and ****ed off at vodacom and employees.
