Bad service from Vodacom n their staff

On Saturday I purchased watsapp bundle for R12 for 7 days and since that day I was unable to use my watsapp as it says I don't have data then I called Vodacom then they said their experiencing problems with it n I was refunded my R12.

Yesterday I purchased minutes for 7 days R45 n I only used it yesterday n today i had R 10 airtime n I made a call to Vodacom number but it chow all my airtime n call cutted. When I tried to make a call it says I don't have airtime. I called Vodacom I spoke to babalwa n he say I will be refunded my airtime within 2 minutes n he will give me feedback abt my minutes dats not working as he send quiry to team leader. After 10 minutes I received SMS saying I HV been recharged with 0 Rand n dere is nothing on my account and I can't even make call as de minutes r not working n no feedback yet. So frustrated I even wanna port my number to other network as Vodacom is not working for me
