Broken promise

I took out a contract with Glocell in June 2016, while taking the phone the consultant told me that I would have two free fixes of my screen back and front during my 24 months. Unfortunately my phone fell and the screen accidentally broke. I took the phone to Samsung this weekend and was told they will only be able to fix the screen in the first 12 months?? Thereafter the cost will be on me? I was told by the consultant at the store this cover is for the full 24 months??? I called Glocell and they are telling me unfortunately they will not be able to assist as I dont have a recording of this being said by the consultant as this was an in store purchase??? So everywhere you go you would need to record your conversation for the other party to honour their side of the agreement? Sadly the consultant did not even give me a copy of the agreement so I am not even able to see what the agreement says? Really dissapointed by the way Glocell can move away from their responsibility towards their customers?
