A nightmare to deal with

Went to Vodacom at the Marc for a contract upgrade, he process was a mess with many people logging into the system. I asked if my contract be upgraded and they performed an 'upgrade' on another number which I cannot recall as my main number is not due for an upgrade.

Now I am paying for 2 contracts rather than 1. I have been to the store 3 times, followed up with the call center to which the response was go back to the store. I have whatsapped the manager and I am still waiting for feedback.

I want the second contract cancelled as this was not my request and I refuse to pay for 2 contracts.
