Vodacom never answers 111 calls and incorrect bill

This is the second time in two days I am trying to get hold of Vodacom. Yesterday I held on for about 15 minutes. Today I am still holding on afte 40 minutes. Always high volumes they say. I'm sure if I phone at midnight they will also use the excuse of high volumes. I migrated and got a sms giving me info which is not what I signed for. Bad service. i'm hanging up now 18:20. Been waiting 44 minutes.
