Bad attitude & failure to assist client

I have been a vodacom client for years. The attitude & bad service I got from their call centre is completely ridiculous. I bought airtime yesterday R12.00 & R29.00 cause I knew I took airtime advance a day before. After I recharged I tried to convert airtime to data bundles via *111# but the service was unavailable then I thought to myself rather check balance cause no recharge message was coming through. To my surprise my balance was R0.00 so I thought maybe the voucher didn't work or go through cause I didn't use it. I tried to put the same no. So it showed it is already used. I called Vodacom as the service provider the lady who spoke to me said obvious it is applications running in the background, I said to her my phone settings (Samsung) I set it that applications only update while m connected to wi-fi so how is it possible? She said there's nothing she can do if I am not understanding. Today I called again to request a service request., a lady called Nokuthula refused to log a request for me said that airtime was R30.00 so I used it on internet. why should I waste my energy and time to enquire about R30.00 if I knew I used the airtime. Was it difficult to log a request?
