Pathetic service and clueless staff!!!

Absolutely terrible service from Telkom. I have done an online order for a mobile device on 20 December 2018. On the 21st an agent had contacted me confirming all my details and the same day my account was debited. They had informed me that the device will be sent in 3-5 working days. I had called telkom back on 30 December. They then informed me that it would be delivered in 3 working days. Still no device delivered..... On 3 January 2019 I spoke to an extremely rude and unprofessional gentleman by name of Warren. He could not assist me in any way and basically knew NOTHING!!! He could not give me any details as to who could actually assist me and eventually hung up the call on me. I called back and spoke to a lady. She checked up on my profile and informed me that they did not have the specific colour in the device. She gave me an option to change the colour which I accepted. She then went on to inform me that an agent will call me to confirm my change. Today, 4 January till 13:00pm no one has got into contact with me. I called telkom again and spoke to Zanele Khumalo. She now has advised me that I need to wait another 48hours for them to call me back. O have requested contact details from Warren and Zanele and both could not assist me and both hung up the call on me. They have no information or idea as to what to do going forward. I am extremely frustrated and disappointed with the dismal service from Telkom!!!!!!!!
