pathetic service - 25 minutes on hold

I app**** for a contract which I got and activated. I now want to port my vodacom prepaid number to my vodacom contract. I call the porting number which is not free, the agent Kim hangs up as she can't hear me. The second time I call back again kim answers. I say I want to port my number she puts me through to contract activation instead. I call back a third time this time I wait25 minutes no answer. I finally hang up. Can someone please contact me to help me do this
