Processed my upgrade as a new contract - no resolution since 6th December

Vodacom in error creating a new contract for me instead of processing an upgrade, to date no resolve has been made. After numerous calls to Vodacom I was instructed to email, and email to *** was sent 6th December and *** on the 8th December (ref 74790). Numerous follow ups on Facebook messenger with the Vodacom Social Media team, and still no resolve! Nobody is reading my email of what is required and getting frustrated! All I require is what I confirmed over the phone which is an upgrade and not a new contract.
