consultant shouting at client

I am disapointed by the treatment i got from Vodacom4U wonderpark. My mom bought a phone and it was not working so she took it back and requested a new one of which they said she will have to wait until the one she bought is repaired.<br> <br> 1. why a new phone need to be repaired? weather it is software or hardware related, she should have been given a new phone to rule out problems with the phone in future.<br> <br> 2. when i enquired on behalf of my mom I spoke to a very rude consultant by the name of Ana, she was shouting me and telling me that I am inconveniencing them by enquiring about the phone. when i asked to speak to the manager, he rushed me off the phone and gave the phone back to Ana. later on a consultant by the name of Armand phoned me back and explaind why the phone needed repairs. <br> <br> It is very inconvenient to buy a cellphone for R6500 cash, and still not have it 6 days later!!! It would have been easier for my mom to have asked for her money back and went to another cellphone store.
