Vodacom repair centre-Bad service

I submitted my Xperia Z3 to vodacom on the 1st of June for repairs. I was never offered any loan phone and I was told that the repair process would take 7-14 working days. On the 9th of June I was given a quote which I accepted right away and I was assured they would place an order for replacement parts on the day. Till this day which is over 2 full weeks later Vodacom is still telling me that they are waiting for parts. What kind of service is this? This has gone far beyond the 14 working day period promised. If there was a delay on the parts how come I was never informed or at least even offered another handset during this period. So I'm currently paying vodacom for a cellphone contract yet I can not utilize any of the services which I'm currently being billed for. No one has contacted me to inform me about the delay. This is the worst customer service Ive ever experienced and my last contract with with vodacom
