bad services

At first didn't want to investigate the ***** which reported in January, I kept on calling they ended up attending to it only in may, It was confirmed *****, now I want my money back, <br> I keep on calling they send me form one person to other no one is willing to do my refund all they do is promising it will be done after 15 days, days go pass and I speak to new person and they say the samething it will be done after 7 days,now when I call they don't even answer their phones, but it's my money I want it back it's not Vodacoms money, and I fail to understand why they not doing their job I sent everything they asked for, this totally a bad services.
