#TELKOMMUSTFALL!! Worst Service Ever!!

I give credit when its due but came to a point that i needed to take this further. i have never in my life experiences such bad service - after all i am paying for it! My cellphone contract ( 24 month) finished in September 2015 where i payed R500 per month. i was told that after a 24 month contract it would automatically jump to a month to month contract, i will get the same package but my installments will no longer be R500 but R349 as the headset ( samsung S4) has been \paid for". October 2015 my bill came to R350. the next month it was R949!! what the heck?? i looked at my itimised billing and it showed above the R350"
