Unsatisfied customer

Wrote my review last month and was contact by a agent with regards to my previous review,agent tried calling me again next day to get more information on the contract we have with vodacom but because I fly I can not answer phone calls the 3rd day agent called again and sent a email.I rep**** on email and tried calling throug vodacom customer line agent there told me there is no number they can give me to get hold of who im dealing with but best advise is i must wait till the agent that's dealing with my complaint call back..after a while I noticed a sms that stated the complaint has been closed,please try to understand how confused and shocked i was ,so to clarify nothing was done just one phone call acknowledging the review and to say they looking into it. I understand agent tried calling an left voice message but please understand as the customer the nature of my work don't allow me to be online whole day so the email I really appreciated that's why when I got a moment i tried making contact back.
