Telkom giving clients wrong information

I am so ****ed this is the 3rd incedant I have with Telkom, first I had a ***** case with them then they debited my account for more then they should have and now the same thing.i am so sick and tired of this **** Network and besides that they are telling me I did not pay in April of which I did coz I made a manual payment, the agent that assisted me told me the April payment was for May how on this earth does this work, then his Supervisor is telling me another story everyone has a different story they do not know what is happening at Telkom its a shame. Oh and the agent that helped me at the store when I went to do my upgrade told me that they will jot debit my account in May but in June they will double debit my account. They took their money in May and June I personally asked the lady if I'm Gona be paying 2 amounts for the old device and new device coz I upgraded before the time. I don't understand this coz I changed my number how can they charge me for airtime and data I did not use how in the hell. And now they are threatening to hand me over imagine I will make sure everyone knows how in incompetant Telkom staff are. The call center agent is telling me they can't be liable at the call center for the lady at the stores actions and that she mislead me. I've been sending emails nobody can help me I really don't know what to do. They clearly do not know what is going on there coz last week when I asked that guy why doesnt it show April's payment he said the app is wrong coz he can see payment on his side but now this agent is telling me I did not make payment mxm **** Network.
