Dissapearing data & airtime

I have been a loyal Vodacom customer for more than 15 years & I have 3 contracts with them

Since from last month I have contacted Vodacom more than 3 times to complain about missing data and airtime on my phone but I was told that my applications on my phone are auto updating. I have switched off my auto updates due to the expirence that I had the last time but they still insisted that it is the reason why my data & airtime dissapear very quicky

On the first of each month I receive R150 airtime and 100MB On 01/10/2017 at 17h05 my data balance & airtime balance was zero. I have never made a call but I only used data I contacted the call centre & I was even advised by one of their call centre consultants that we want to rob Vodacom. From that day I promised myself that I will never again call Vodacom because their client service sucks, they are impatient on explaining to you

This morning at 07h05, I loaded airtime of R29.00 & my balance was R33.73 & I bought 30MB for 3 days for R4.50 now as I am typing this(10h45) my balance is R3.17. The data that I bought now is not reflecting

I am really tired as this happens all the time I need this matter to be sorted or I am cancelling all my 3 contracts
