36 Month contract now all of a sudden a 38 month contract. No responses! BAD SERVICE IS AN UNDERSTATEMENT.

I have a rental agreement for 36 months for a fridge, End of November should have been the end of my lease and therefore ownership transferred to myself. They now want me to give notice only in January 2019 which means I will be paying for 38 months and not 36 months as per contract. I have been in contact with Teljoy accounts as of before 21 November in this regard. They do not respond and I need to phone them all the time. My fridge has a defect and now that I am withholding payment until they can give satisfactory feedback on my account query, they will not be logging a ticket to repair/replace the fridge.

Really bad service. They are quick to follow up and send smses, but do not respond to customer concerns does not matter how eager the customer wants to resolve.
