Inconsiderate, rude and ineffective

<p>So a sales guy byou the name of William just called me on MY number and requested to speak to my gran, she has given me authorization on this account probably 20 timeso and each time Vodacom promises they've made a note and it will not happen again. Thus time the agent not only refused to help tell me what the hell it is he wants with my gran, he also put the phone down in my ear!! I have never seen any company allow that with its customers!! I have been with Vodacom more than 7 years!! Is this what I get? I'm not sure I'll be staying if that's the service they pride themselves in!! </p>
