Management hiding behind their employees

A group of us are embarking on a mountain climbing project to raise money for less fortunate individuals and I made contact with Drone world to investigate their silliness to provided a DJI action sport device to capture the event. I called the Sandton branch on Monday explained our requirement and was given an email address for a lady called Hanna. I asked for her surname and was told we do not give out surnames or phone numbers! I duly sent a mail detailing our requirement and as I not received a response called the following day Tuesday 20th to confirm receipt. I left a message requesting Hanna call me. The lady in customers services said she would ask Hanna to respond to my mail. By Wednesday I still had not received any feedback and again called to be told Hanna will be asked to respond to my mail. Today is Thursday and I called Head Office in Cape Town and asked to speak to Hanna. Again I was told that she only responds to emails. ( Which she Cleary does not !) I then asked to speak to the General Manager and was told to send a email. After some further conversation I was put through to Liesel in customer services. I explained the purpose of my call and frustration as I had not had any feedback. She said if they ( Management ) were not interested in the context of my e mail that would not respond as they get 100's of emails! Really - Is this customer service. I cannot believe in 2019 supposed "Management" still hide behind employees to protect themselves and their identity. The great shame of course is the DJI product is world class, sadly the Management team supporting it @ dreamworld are anything but world class. But hey I am only a customer.
