Vodacom-lack of clarity and capacity -dubious??

I phoned Vodacom today to try to find out hat happens to the 391 voice minutes left over from my January account. After two calls - the first after talking to a lady who could not give me her name until pushed - and then left me hanging after apparently redirecting my call, I am still non the wiser. I have a Red select + package which gives 800mins and 4GB of data each month At the end of January I had left (according to the Vodacom App) 69mb data and 391 voice mins- Bill was R783 On first Feb I had (according to the app) 4.02Gb data and 842min voice Bill R783 On 2nd Feb I had (according to the app) 3,78Gb data and 729mvoice Bill R433 Go figure... To try to find out how this billing system works is just about impossible This makes you wonder about the credibility of Vodacom Aside of the fact that cell-phone and internet signal is contimnually deteriorating,erratic and many times non existent to say the least at Hartbee****rt Dam (where I stay)as well as in the Madikwe Game Reserve (work) , the company appears to be going down the drain. In Madikwe Game Reserve on frequent occasion, one can be without signal for over 6-12hrs - why - no one knows?? It is highly probably as is evident in the Vodacom customer care department that the employees just have not got the capacity or inclination to do the job!! But we pay for the service .........???
