Waiting for my money to be paid back!

I use to be on the Smart S package, then i went over to Smart L as Vodacom said it would be cheaper, which it wasn't so i migrated to Smart S again. Vodacom said they will not charge me a migration fee as i use to be on the Smart S. the end of may came and they charged me R 1 275.00 for the migration. I contacted Vodacom and firstly i was sent around to so many people, eventually someone from accounts told me to send my bank statement where the amount was deducted from to [Email Removed] which i did, but my email was not received for some reason, i then spoke to Winny Mbalati and she told me to email her my statement (1 June 2015) and she will send it on, she confirmed over the phone that she received my email. She also advised me my money will be paid out in 7 working days. Yesterday 9 June 2015 which is the 7th day i called to actually find out that Winny Mbalati never received my email, yet she confirmed on 1 June 2015 that she did. I am still waiting for a manager to call me and that didn't happen either. I'm fed up with vodacom and SHOCKED with their service. I still have not received my money. I want this paid to me TODAY!!!!!
