No follow up & only excuses from Vodacom

I logged a call 3 weeks ago for a sim card that is not working internationally. Still out of the country and Vodacom have no idea what the problem is. They only have excuses, no reference numbers to follow up on incidents, only date and time of call and agents name is provided. When you call back, there are no agents by that name. Conveniently you are in a different call center. Absolutely no accountability or ownership from the staff. They cannot give you a time when it would be appropriate to follow up. They never keep their promises.

Utterly useless service from Vodacom.
