Right, I think I need help...
I've recently finished my 18 month contract with three and have now joined Vodafone.
My first payment for the contract was January 2008 and the last payment was on May 2009. This makes 17 payments by direct debit and I understandably need to pay one more. However, today i received a bill through for two months payment. This means that I would have made 19 payments on my 18 month contract.
It doesn't end there, I rang up the customer service and they went on to say that after I had paid for these 2 months, Another payment of £26 for my line rental would come out on the 3rd of August.
Now correct me if i'm wrong, but this makes 20 payments for my 18 month contract. What is going on?
