I want my money back!

I have logged various complaints with this company on the overcharge of R349 on my bill at the beginning of this year. I have followed up many times but am told that the complaint is closed due to them not getting a hold of me. I want my money back!!!!! I will be going to the Ombudsman and every social media platform to tell everyone how useless your service is as well as your call center staff. It seems that basic education is not a requirement for these people!
