Pathetic!!!

Let me start by saying. If I could give a no star rating I would. Service absolutely pathetic. Disgusting to say the least. Every month I am doubled billed for 2 fibre lines of which the online agents did a whole ***** up. I called the billing department they gave me reference and told me it was sorted out and correct. Even the branch manager at one of the stores helped well that's what he thought. I get billed again double looks like the credit was not passed even though they said it was. I am working from home. This is extremely annoying. I cannot afford those double bills nor can I afford the line to be off because of a double bill of which all your *********** staff has created. Not once can someone superior call me and assist me the way they should. They all hide behind the useless dahm agents. !
