India Mags — Took money and now they are not lifting the calls and replying over email

I have paid them full amount for two magzine and also dropped them email that all payment is done. They said it is lockdown in 2020 so once resumed they will tell. It was last year and after constant follow ups they replied that lockdown is over but the magzine you order is not available so select different one. Then again in 2021 I paid them additional amount for new magzines. It has been 15 days now and still they are not confirming my order and reverting to the emails.
