Mtn complaint for bad service

I took a contract with mtn for an hp laptop in 2014.The laptop failed to work the very same day i took it home.The computer ran slow and i reported it immediately.The laptop was taken for repairs.It still had the same problem of loading slow.I immediately contacted the hp repair technician i was referred to by mtn immediately via email.She failed to respond to my email.I went to the store to report and was referred back to customer care.When I called customer care i was referred to contact hp directly.I then decided to stop paying the premium as i was not getting assistance and had been loyally paying for services i had no pleasure of enjoying.I contacted customer care on the 4th October 2015 regarding my queries.I was then once more referred back to hp.<br> <br> Mtn has failed to come to my aid for almost a year now.The guarantee for the product has lapsed and the product has never worked from the onset.When I went back to yhe store where i took the contract,I was advised to take the laptop to repairers at my expense.I have been unfairly treated by this company.Please assist.
