Bad Communication

I logged are call to have my service downgraded due to financial issues mid May, I was told the service will downgrade in June, come June am still been charged for the same service and when I complained they told me it will start in July, we in July still same issue which no one is willing to assist and coming up with different stories both Accounts and Sales departments are just pathetic they don't now what to say one says down grade will be 1st of August another one saying end of August and no one told me that service will not downgrade when account is in arrears the arrears caused by them by miscommunication and not downgrading my service. I want my service downgraded and the incorrect amount rectified and the arrears from June removed as its caused by your sales department. I will only make the July payment of R700 once you remove all this nonsense and I want to be called back with proper feedback not the bull **** you guys telling me.
