No record of call or parcel

On Friday _ I purchased and EPAK and Grahamstown - and paid for express delivery. I phones the national Call centre Number - I was assisted by a gentleman who took details -the parcel was not collected on Friday afternoon - but because I phoned late _ I left it until Monday. On Monday I have to make two phone calls _ both people treat me as though I am not telling the truth - I have a PAKED number (***8) - (By the way - there is only one number on the EPAK - it has 8 digits - your call centre asks for 7 and your switchboard - says - please be ready with your 6 digit number - which one) BUT- you have NO record of my call - I have an invoice to prove that I paid for it. So am I imagining it all then ??? - that I only phoned you in my dreams - your call was dropped somehow and it did not registerd on the system - I hope that you are now going to pick up this parcel _ If I wanted to get treated like the post office - I would have gone to them - very poor service indeed. Please do not send me a 'cut and past\ generic reply - have the courtesy to phone me. Thank you!"
