automatic contract renewal

I immigrated from South Africa to the Netherlands over 1 year ago.<br> Before I left I went in person to Vodacom,Cresta to make sure my contract would not be automatically renewed (as this had happened before). The sales rep at the store said that Vodacom should not have previously automatically renewed my contract & that I would not have to take any action to make sure it is not automatically renewed once again.<br> <br> I got an invoice from Vodacom on 2014-08-07 stating that the total remaining amount due was R900.50 which I payed to them in that same month. I sent several emails to Vodacom to confirm the money was received & the contract was settled, but I received no reply from anyone.<br> <br> My contract ended September 2014 & I was still getting R326 debited from my account monthly.<br> Today I found an email in my spam stating I owed R2935 to Vodacom.<br> I called the callcentre who confirmed they had received my final R900.50 payment, but because I never went in person to cancel my account it was automatically renewed. I explained the situation & the rep said because they have no proof of what the sales rep in Cresta said I will be liable for another full term (2 years) of cellphone payments.
