Zandi dropped the call on me

Today at 09h09am, 28.12.2015, I called ***and I held on for Reception, as option 4 for tracking was re-routing, I wanted to address my concern with regards to delivery notification with Ref 468565 that I received today. I wanted to advise them that the delivery should me made on 30/31 December 2015 as there is no one at home, or delivery can be made 5h30pm from 28-29 December, however there was a line problem, instead Zandi chose to drop the call on me. This is disgusting service and wreckless attitude and disrespect to clients.
