UNHAPPY CUSTOMER FIBRESTREAM ISP

there customer service is absolutely terrible as an internet service provider (ISP) they have simply failed to even load a simple debit order and i currently now have had no internet connection for 4 days even after making a cash payment to them, after continuously complaining they have resorted to blocking all emails and all phone calls and they say it has to do with vumatel which is utter ******* as i did call them and according to there records my service is active. previously it had taken them 2 weeks to lodge a faulty router which we had to pay for. as long as i am alive i will never ever recommend them to anybody, they have no sense of responsibility it always just blame shifting.There should be a law in place to cancel contracts due to poor service.
