Bad service and customer explotation

I am very disappointed with the service from telkom. I app**** for ADSL line in January and till today line not installed. They told me there is a faulty underground cable which it’s over 3 months now and they still have not done anything with it. Sadly they have started charging me for a service that I don’t have. I think this is the fall of Telkom they are truly running their business to the ground. They don’t care anymore about their customer. Someone need to investigate we as community do not have power to fight with them. I wish someone can help me to stop them from charging me for a service that they have failed to deliver.
