I've been on the phone from the 1st June everyday, for my upgrade with the Mtn Upgrade Department and every time I call they tell me they don't have access to the new elula system. And someone will call me in 48 hours, no one called as yet. Today 9th June

I've been on the phone from the 1st June everyday, for my upgrade with the Mtn Upgrade Department and every time I call they tell me they don't have access to the new elula system. And someone will call me in 48 hours, no one called as yet. Today 9th June I've called again, the upgrade department and they advised I call the customer service, they also won't be able to assist me, transfered me to the retention department, been in the pH for an hour and no answer. This is rediculous, I need someone to call me back from the retention department. As I am very frustrated, because I've been calling Mtn for a week.
