Poor customer service and incorrect billing

I app**** for a contract phone online and I have not received the phone, yet vodacom is billing me for it. I was advised to email *** to log on query, of which I did. Lennon Samduth respond to my query stating that their system is s showing that I received the phone. I request a full investigation and proof of delivery. Until now, nothing has been done, in fact my query was closed without a resolution
