Bad service and being ****** money

I signed up for a contract with Telkom last month I was not asked how much spent limit must be set on my account I tried calling in more than 5 times no one was able to change my spent limit until I spoke to the one consultant who said she changed my spent limit to R50 and it will reflect on the first of July today is the second of July my spent limit is still R1500 pathetic service I got do I have to call in a 7000 times before my spent limit is changed I guess this is how Telkom is robbing us knowing very well you will end up spending that 1500 limit not being aware and youll have to pay which is more money for them this is pathetic next thing Ill be told no your request can only be active next month which is **** I want my spent limit to be adjusted immediately I called in last month and its not update fix your mess telkom and stop robbing your customers.
