Telkom internal ****

Hi i would like to launch a complaint about Telkom cellphone services over a complaint I launch on their community but taken forgranted ,over a bill they sent of which was unfair till this present ,say your on a contract of which on the terms your set to set a spending limit of which its on the telkom network service which is used as your talk time which I did and it was R100 .At first i lost my simcard went to their premises to recover it after i activated it ,but because a spending limit is set on the service and remember mine was set as a R100 I made calls and later discovered that they sent me a bill which is a R1800 or something which they normaly notify me a day before the debit order which i was confused to actually ask about it,I called but couldnt get help from them which i think its an internal issue thats why it wasnt addressed and its the second unfair debit order ,how can i used a spending limit that actually is half the price of the actual cellphone device so of which I could have done, on top of that they called and offered me 10gb extra data which i disagreed to take then later they charged me for it mind due I've been a telkom customer for years all this is messing up with my accounts, my credit score,my bank account, my life in general because all the debit reversals i have to go through each month so unprofesional and bad customer service ,ill treatment you mention it i i just need it dealt with once and for all I really need help because its blocking other business factors I WAS ****MED
