Pathetic Services Rendered by Vodacom

Got my son a contract from Vodacom - Blackberry Z3 (6th October 2014). Never told there was a backlog on the specific device and received it 6 weeks following contract start date. 6 months later the phone started stalling and would suddenly \die". Took the phone to Vodacom - Vereeniging - who send the phone to Cresta. Three weeks later I received an sms from Cresta noting that the phone was repaired and to be sent back to Vereeniging and Jaco told me it was not there - 8 May 2015. Followed up with Cresta on Monday ****h May) - and was informed that it was definitely sent to Riversquere. Phoned Riversquare again and told it was never \""Logged In\"". Nightmare does not stop there however. When my son switched on his \""repaired device' the phone stalled yet again"
