Extreme poor delivery service and customer service and not knowing the business

Signed up with Web Africa on the 16/02/2018 and up till today 05/03/2018 (17 days later) no phone call for delivery of the router has been made. When i called after the 5th day as the delivery should take place after 3 - 5 working days when all documents and information has been submitted, which they were on the 16/02/2018 I asked for the sales person Daryl to call me back numerous times cause ether he was busy or he wasn't at his desk cause i needed to know whats happening as its going past 5 working days now. I called on the 28/02/2018 and spoke to another agent (Not Daryl as his never available nor does he get back) who put me through to operations who was told to assist with the ETA of my delivery, I spoke to Ayesha from operations who inform me that the delivery wont take place as the payment of R199.00 did not go through and that they cant tell me why as all the card details were given when they needed it. Was informed that the data could have been captured incorrectly and that could be the reason why. Then was told to make an EFT payment and send through the proof of payment of R199.00 and that she would chase up the process and should have the modem by Friday 02/03/2018. Friday the 02/03/2018 a SMS was recieved stating that the modem should be delivered within the next 8 working days even after the order was messed up in the first place by web africa. I called in today 05/03/2018 to find out whay is happening and the sales Person Jade said he cannot assist me as its out of there hands and has gone to Operations ( In what business do you tell your client you cant assist them and that i need to speak to another department, Are all these people working for the same company) and then was transfered to another gentelman in the operations department who informed that he cannot give an ETA time when delivery will take place and that i must wait for the courier company to call to make a date and time of delivery and the more i want to know what is the delay the more hesays i must wait for the courier company to call. So i asked to speak to a manager and stated to me that not even the manager can assist on the delivery on the modem and if i want answers why the delay in the delivery due to an account problem then i must speak to the accounts manager. Then he dropped the call on me as i could hear he was getting annoyed with me and all i want is to know what is going to happen due to the delay i need the modem not within 8 days as 8 working days would be the 14/03/2018 almost a month after ordering the modem.
