Magicpin — voucher not applicable

Address:

New Delhi, Delhi, 110027

I purchased a voucher of bookmyshow from magicpin on this friday i. E 5th of september 2019. I clicked on redeem it and copied the voucher code. When i entered it in bookmyshow it said the voucher is invalid. I tried several times but it failed. Then i submitted a complaint from the option helpdesk and was told that you will recieve the response within 24 hours. It has already been 2 days. There is no email nothing. Atleast be a little responsible towards your customers and solve my problem
