Check those statements

I have been on a contract with Vodacom for years. A few months ago my monthly statement suddenly up by about R300. My fault I did not check the statement. Payment goes off by debit order. The same the following month. Checked. Saw I was billed for Vodacom Live and 2 other subscriptions for which I did not register. Went to Vodacare. They 'cancelled' subscriptions and Vodaphone Line but said they could not refund me ! Next month ok. Then this last statement Vodaphone Live is back !! So sick of this company. I am sure I am not the only one !
