DISGUSTING SERVICE FROM RAM - DELIVERING OPEN PACKAGES

I processed an Upgrade via Vodacom with the request that the Courier must phone me a day before the time to ensure my location as I travel between offices, this did not happen. I received an sms on the day of delivery, luckily I was at the address required. The courier phoned me to say he was here and confirm location. I went outside the office building to find him parked in the road with moving traffic (there is parking available), making it dangerous to stop and "do Business", On arrival at the vehicle 2 men were scratching in the back looking for parcels. The one gentleman called a number and the other got the parcel, when the parcel was brought to me it was already opened (the sealed bag) he then put the bag on the road and held things in his hand wanting to give me a bunch of loose items which he was trying to put an elastic around, I asked him what he was doing and he said he had to open the bag to get the invoice, I asked him how is this possible as Ive never received an open package, how do I know what was supposed to be in there, I then said I wasnt going to accept the package as I dont know if it is correct and especially being contents from Vodacom!! He said its fine phone Vodacom. I tried to phone RAM and they were phoning me at the same time, I explained what had happened wrt me not accepting the open parcel, she said it wasn't right and got the gentleman on the phone, she told him what I had said obviously not knowing I was on the Phone too, he blatantly said "SHE IS Lying". When I then spoke and told him I can sue him for deformation of character he then apologised for saying so. The lady also appologised, but its not acceptable!!!! He then Ordered me to come back to the gate and take the parcel. I find this unacceptable and unprofessional service!! I am now supposed to give such a person my ID and personal detail, living in the current ******** activities as we do I do not feel safe doing so. I have phoned Vodacom and reported this to them! I find this utterly disgusting as now I don't have the goods I ordered, I've been blatantly called a **** and exposed to this unpleasant incident!
