Rude - hung up phone on me

I was on the phone for 3 hours trying to cancel a debit for the last 11 months ... this was my 7th call to Vodacom ... everytime I call they say it is cancelled but it is never cancelled .. I get money deducted from account every month

Today I again spoke to a Vodacom customer care consultant who was very frustrated when she answeered .. then she cut the call on me ... it was not a lost line but she cut the call

Very unproffesional and rude

I wish I got her name ...
