3 MONTHS WITHOUT A PHONE

This is my third or fourth Hello Peter report on Vodacom. JOB NO ***5. My Blackberry z30 has gone in for the 6th time for the same fault,today is three weeks ago again, Dumiso at Vodacom 4ways is \helping me"";and guess what;Dumiso isn't there and he will only be back on Monday.I am sick and tired of this and I cannot understand how Vodacom can not just replace my phone with another model since the Z30 is CLEARLY flawed!I don't keep sending my damn phone back because I like sitting without one;IT IS NOT WORKING YOU IDIOTS! I want another phone and I demand that someone in top management sort this out - IMMEDIATELY - I am tired of dealing with ***********;rude idiots of staff in call centers and repair centers!!! I will be putting a stop order on my bank account today so that Vodacom cannot collect any debit orders for payment and I will not pay until this is sorted out !! """
