THIEVING COMPANY

I did an online upgrade to a Samsung S8 and arranged for the parcel to be delivered. Upon receipt of the package, I opened it and found that there was no phone inside. The only items in the box were a simcard, an invoice and a Vodacom pamphlet. We have sent Vodacom numerous mails, made countless calls to the customer support etc. etc. but they just ignore everything. The worst part is, on the account we are charged as if we have received the cellphone. HOW CAN I BE CHARGED FOR A PHONE I NEVER RECEIVED???????
