Missing airtime issues not resolved because of bad service from call centre consultants.

I received my monthly airtime of R110 today and my phone was off and data was off the whole night aswell..when I woke up I switched on mobile data with no data bundles to check whatsapp,which happened for a couple of seconds and mind you I didn't even send any message on whatsapp only to find out that those couple of seconds chowed about R16 of my airtime,I let it go and I thought it was something technical.After a couple of minutes I switched on mobile data again for a few seconds to go onto the "myvodacom app" still for a couple of seconds,it chowed more than R10 of my airtime..I called the first time to complain,the consultant said "she does not know exactly what chowed my airtime" and she said that I had internet charges but I haven't been on the internet today.When I requested an email of a breakdown of my charges she put me on mute for long and I feel very offended by this as the call centre agents treat people like they are stupid when this thing is customer service and im beginning to question Vodacom's loyalty to its customers..I called again for about 4 times still the second person didnt resolve my problem.I cannot have missing airtime when I didnt do anything with it and receive such bad service from the vodacom call centre that is there to assist me with customer services and still have my problem unresolved..I have been too understanding as a customer to endure this kind of a treatment and received no positive outcomes in the end.where are the call centre managers on floor at that time to even assist with these problems and their *********** consultants.I need a solution to this problem and I do not appreciate being treated like this as a customer.I have been with Vodacom my whole life such I haven't seen before.I had heard people complaining about this problem on facebook for weeks now and it hasn't happened to me so im wondering why they still have such problems and this is forcing me to seek another service provider because in my books this is abuse.we all work for our money for a service provider to bill incorrectly or whatever happened and not want to resolve the matter afterwards..Im so disappointed and hurt coz im a student and I needed my airtime to research schoolwork.So disappointed that the matter is not even resolved by now.
