No customer service - unable to upgrade

Vodacom has migrated my account to a new system that none of the stores that usually process upgrades are able to use. I have spent 2 days and endless phone calls and emails to various Vodacom call centers and customer services, and still no one has been able to assist or taken responsibility for assisting me with this upgrade. I have been told on numerous occasions the reason for the problem (being the migration of my account to a new system), but no assistance has been provided to solve it. Why should I, as the customer, have to spend over 2 days trying to solve Vodacom's system issues? 2 days, 9 phone calls and 7 emails later I still don't know what is happening with my upgrade.
