Rude Call Centre Agents that cannot do their jobs.

The call canter agents are useless and of no assistance. I had to wait 15mins to speak to someone then they hung up the phone on me. I changed my address on Friday and was promised that my order will be delivered to the new address on Monday. On Monday I receive a call from the driver and he was at the wrong address... like what nonsense is this??? I called 3 times to just be able to speak to an agent and change my address and still it was not changed on the system. Do better and treat your customers with respect.
