Poor poor service from Vodacom

We went overseas and struggled to close our Vodacom accounts. Vodacom kept the debit order running. After months of furstration we closed the accounts and Vodacom paid back our money. We are now back in South Africa and want to open Vodacom accounts again. According to the system, my account is handed over to the legal department. I spoke to Sylvia on Friday and she confirmed that my account is paid up and that all is good. She said it would take an hour to do the system update, but now 5 days later and 7 calls to Vodacom Legal, no succes... What should I do, open an account at MTN???
