Ackermans connection wonderpark

I bought a phone for my child after a month she complained about it. And I took it back to the shop for them to check it. As they said if the phone is a physical damage they won't fix it and we agreed upon that. Then months go by till I return to the store only to fine that the phone was physical damage they say. I said okay can I have it back then now the story changed to I have to pay for it so they can return it to my surprise they didn't say anything like that in the 1st place it's almost a year since they took that as I told them I am not going to pay for it I want that phone back. Ackermans connection are ****mers and I want that phone back. To think of it such a big company but they **** people taking from the poor!
