bad service from ccd couriers

On Tuesday the 14 of Apri 2020l I received an sms from ccd couriers regarding my Mweb router deliver, then I called the courier to inform them that I did not have a proof of residence on hand, I can only email it to them, they gave me an email address and I emailled it before they came to deliver. I could'nt print it out due to the lockdown and they said they will Inform the driver that I need to give him an Id book copy only. They came to deliver and the driver didn't know anything and didn't wanna leave the router with me. I send another email again with my proof of address attached and still I haven't heard from them. I called them again and I was assisted by a lady called Leah and she said I must foward all the emails I've send , they need to investigate the matter coz I will have to pay for the second delivery coz the first one Is free. I call them every single day and they say I need to call Mweb to reschedule another delivery, I did that and still I haven't heard anything from them. When I call them they always say they will call me back. I'm working from home and now I cnt work cause i'm waiting for the router, I'm behind with my work. I called them even today and they still giving me the run around.
