On Air tv ******s

I have a problem with the company, i canceled the order the same day I took it. Then they left the package at home without having my copy of ID. I called the customer service which took longer time to answer. The customer service agent agreed to cancel the order but i had to pay R150. Now i have been sent a message to pay R350. R350 for what your package is sealed, i have not opened it. On Air payment request from On Air. Amount: R350.00 Reference: OA-***1-1 https://swiffy.co.za/u/RN9l32PL Im not paying that your package is sealed not opebed
