Terrible Service

Called in about 2 months ago to change my banking details and all I have received has been nothing but poor service. 1, the consultant changes my acc no and not the bank name, 2, two months later my account is disconnected without informing me, 3, I receive terrible service from the manager at the billing dep, 4, I am informed to make and cash payment, 5, my account is converted to cash and not D/O as requested, 6. I make arrangements to run a D/O on the 8/12 and move the D/O date to the 23/12 moving forward - we agree, 6. I am double debited and 7. A call center agents puts me on hold without telling me wraps a call on me 9/12. Thanks for the arrogance from vodacom and plz note that u have lost a loyal customer over terrible post service support. I have not even once been given an apology instead the manager at the billing department made it clear that it was my fault - how so, I am still trying to figure that one out when all I asked for was my banking details to be changed on the system and someone at Vodacom stuffed it up - the caliber of your leadership in quite intriguing.
