Billdesktatasky — Tata Sky DTH recharge not credit

When I clicked the option to recharge in Tata sky Dth app they guided me to browser page and I selected Google pay as payment method and then they directed me to a gpay account of a name (BilldeskTatasky) and I have paid 320 and my money is debited and now the recharge is not credited and also finally finding that the gpay account BilldeskTatasky was not for DTH !
I find it absolute fraudulent from Tata services !! I need my refund asap !
