Mswipe Technologies — System halt ikek tamper sr 0x[protected]Reason: To get Amc at any cost)

I am facing the issue with the machine. Machine shows the following error "system halt ikek tamper sr 0x00000103". This happens now because i refuse to pay any amc which is said free at the time of purchase. Rental Free & No Amc is told at the time of my purchase of device in june2021. now after 1 year they start asking for amc everytime & i told that it was free as you said at the time of my purchase but they deny now i talked with some other merchants too who are facing the same problem & this issue comes only when we are refusing to pay amc. Kindly help me in this matter as i paid around Rs7000 to buy this device & now after 1 year they have stopped device just to take amc which was said free at the time of purchase.
