Disgusting service yet again

I called Vodacom 3 times already to cancel my 3 contacts as there rates are far to high. 1st I held on for 30mins only for a Zanele to answer and pretend she can't hear me and put down in my ear. Then I called 2nd time and got cut off as the consultant answered. 3rd time I get through after holding 23mins and Andile tells me he can't help because his offline. He said he can't even return my call. What kind of disgusting service is that. He said I should call again when ever they back on line??
