wrong billing and very very bad services

i have posted on this page about my husband unresolved vodacom contract that he took from Vodacom has not called to resolve this matter , i am taking this matter further now . i am billed 400 over 90 which was the initial amount that i have agreed upon my phone has been closed for more than a week now , all i want from Vodacom is to close this account and give me my number back because i cannot pay more than i should . if this is not resolved i will be taking this up with my lawyers and credit ombudsman.
