3 days in a row 45 min waiting in line no answer

I have called 3 days in a row being kept on hold for up to 45 min when they drop the call. All I want to do it switch my debit order to another account and query my account which has been debited twice. Then Vodacom have the cheek to send me a courtesy sms asking me to rate their service. What on earth must I do to get through to these people? Shops and Service centres can't help they say I must call the call centre. One person even told me \it's okay to wait. The call if free from your Vodacom phone!"The call might be free but my time isn't.<br> <br> Vodacom is an embarrassment and a shambles. I wish I had never gone with Vodacom."""
