Terrible Management

I bought a vodacom recharge voucher which was invalid. Pick and Pay blamed Vodacom and Vice Versa. Manager is NEVER available. assistant has a no care attitude and staff who answer the phone are rude and shout WHAT instead of pardon. This is not the first time I've had issues with this branch. A week later and ive still not heard from Management. Please.... Head Office needs to address them as this sort of service is unacceptable. I cannot afford to waste my money this way.
