No Feedback from a Team Leader at Vodacom Retentions

On the 16th of January 2018, I spoke to Webster. I was upgrading my two data lines, of which the upgrade was supposed to go through on the 1st of February 2018. Only one line was upgraded to a package with a price we did not agree on. I have been calling Vodacom to get this resolved as I am still on the old package which is a huge inconvenience. I was told Webster is on leave. The agents I have been interacting with tried to help and escalated the query to his team leader named: Maria Mosoeu. She promised to listen to the call recorded and give me feedback. I have been waiting for her call from the 06th of February 2018.

Can some one from Vodacom take ownership and assist me further. I need to compensated for this inconvenience.
