Bad line, Bad Service

This is real bad service when you pay for a 10mb line but you only get a speed test of 0.62 or maybe with luck 2.3 and on top of that you ask numerous times to rectify the debit order and then the want to switch you off for there neglect for not completing the change after they promised that this should not be an issue again. Then they still expect that you work on a bad line as "the tower is over crowded". You can try to call but will only get hold of someone after an hour or two and then they can't assist then you get put on hold again, that is even if you are lucky to get hold of someone.
