Vodacom - *******

My dad took a contract in 2015 December and called to cancel the contract in 2017 October. A few days ago he received a call from an attorney saying we owe almost R1900 for non payment. I spoke to Robin at vodacom who told me someone will call me. 3 days later I didn't get a call I called the attorney on behalf of my dad(she spoke to him and got his permission to speak with me) and the lady firstly called out the incorrect ID number to. Me and then transferred me to a lady Melinda of Burnard Raaff that was so rude. I asked her to logde a dispute for me which she refused to do and a copy of the call which she said she cannot provide .. I got off the call asking for an ombudsmans number and she refused to give me the details to contact the ombudsman she told me to find it myself.. This is effecting my dad's credit history. I am. Really disappointed in the service I received. My parents are old and the manner in which this is being done is absolutely unacceptable.
