No response from Vodacom

I have been trying to resolve an outstanding account since January 2017, due to a technical fault my line was cut, I was not willing to pay my Red Vip account for that specific period. Vodacom kept deducting their fees with my line disconnected, I have made numerous calls to call centres and visited numerous Vodacom branches with no success.If I owe you money, call me back to resolve this case. Please call me urgently. Thank you.
