No Service at all

I recently ordered something from Next for my daughters birthday. I got an email from Dalene Sithole asking me to pay an invoice for customs clearance however there was no invoice attached so after a few back and for the the invoice was finally attached. I explained to her that the parcel was urgent and I wanted it in time for her bday. Immediately paid it on Friday morning and sent through POP. I then asked when I will get it no response . I have tried calling the help desk again on Monday no help offered I got transferred so many times to international then I was given a manager number this is the number *** who I have tried so many times with no response since Monday morning. Dalene responds to say the funds only reflected yesterday so nothing was done . I tried calling her so many times to get some answers about process how long what next there’s actually no one that can help . This is such shocking service I keep getting automated emails saying I still need to complete a customs form and invoice I don’t know what this is about as I already paid it it also says complete a form and there’s no form to complete it would be nice to beable to speak to someone who is willing to help who knows what’s going on who can explain the process etc and give an indication of timing so now I don’t know what to do or who to call as there is no response from Skynet
