Contract renewed without my knowledge or consent, and still cannot rectify after 18 months

<p>The only reason for signing the original 24 month contract was to divide the payments for a new Macbook over that period. I had a calendar reminder on 20 and 22 months to make sure I cancel my contract as I would not be needing it to continue. On around 20 months, my monthly debit was half the amount. On calling in to find out why, I was told that it's because I had recently upgraded my account to a different and new 24 month contract. After 3 months of trying to get any coherent information from the ***** division, I was told to go into a store so they could assist me. THe manager at the Constantia branch was amazing and did his best to assist (even emailing me and following up within the next 2 weeks). Alas, nothing has happended in the 13 months since. The problem is that I have moved abroad to the UK a year ago. I called ***** last year from the UK and they asked me, after explaining to them that I am in the UK, to please go in to my nearest branch and they will assist. Really?!!!!</p>
