No one calling back - Nombulelo where are you?

I have been assisted by a Wonderful Retentions lady Nombulelo (KZN branch) with my account she spoke to me the last time on Friday after noon. While we where discussing the agreement the line cut and I was not phoned back. Now I don't know if the agreement has been concluded or not. I received an sms to say my payment plan changed but don't recall to agreeing to this without it being sent to me to review. My worry is that my packages will be downgraded (less min and data) to accommodate the lower monthly fee. I phoned on Sunday and was told a message will be given to Nombulelo to phone me back. Then I phoned again yesterday and was told the same thing. I have left at least 3 recordings to ask Nombulelo to phone me back. Now at 17:30 a kind lady by the name of Khanyi tried to assist me but could not see any of the deals Nombulelo loaded for me. She said she would ask her to phone me back and would escalate to a manager to phone me back. Well I am still waiting unfortunately as I was told management is in a meeting. I have been a loyal client for more than 17 years and would really like to remain Vodacom's client if they will give me the opportunity to conclude the retentions deal.
