Customer Care - is non existant

Data has vanished and all my airtime depleted! This is unacceptable. The call centre agents are located all over SA and keep referring to another who they cannot seem to locate when you call back. I got through to Cape Town, JHB and KZN all in the space of 20 minutes and 4 calls later!!! Still query not resolved but I received an SMS stating query is resolved and I must rate their service! Ludicrous!! Now there are 2 cases open but neither resolved. Initial query logged 5 days ago. A manager needs to call me ASAP to resolve this query.
