Dissapointed

I'm so dissapointed by Capitec's service,I bought an airtime R30 and R12 mtn via cell phone banking,it didn't go through yet they deducted money from my savings account,I visited the branch and the consultant did a follow up and told me that they investigating and I'll be contacted within 4 working days,I waited and waited for their call,I went back to the brach,I didn't get any help,the consultants that day were very slow,when you think that they'll call your ticket number they'll just stand and go to the back I don't know if its their office or what,they'll leave us sitting there and waiting for them,its frustrating,even now I'm still wondering what happened to my airtime
