Pathetic service provider battling a year with new problem

thank you Vodacom this is really getting upsurd yet another new year and this would be almost a year I am battling with this pathetic service provider paying almost a year for something I can not use. Empty promises every freaking day and the service is just getting more pathetic I can not imagine how many clients vodacom is losing and the best part they don't care for one of there clients like me battling to get my stuff sorted every time someone new and every time empty promises so yes if I could I just want to give vodacom's stuff back and get another service provider. So please vodacom don't try phoning me if you did not get your pathetic story straight. Can anyone tell me where I can lay a complaint against vodacom I am really fed up
