I have been trying since the 20th of November to get my line migrated to my new address after been told by their migration team that it will be done on the 15th of November. After 100’s of calls and messages I was told it will be the 1st of December. Today I still do not have my line activated but their debit order has promptly gone off my account. I am not allowed to speak to anyone senior as they always in meetings. I am now looking for someone to call me and assist me as I am wanting to cancel this line and will be contacting an attorney on Monday as I am being charged for something I do not have!!! Absolutely apathetic they are!!!
