Regarding failed transaction through Google pay and BHIM UPI

I visited Domibivali East MacDonald in Dombivali and palced the  order the amount was 260 n open google pay for sacn thier QR code for payment… But when i scan thir QR code n paid amount… Their machine gave recipt that transaction is failed but… I got mst from google pay n alos from the bank that 260 rs was deducted.. Then macd wroker saide rhat thier some net work problem so i use BHIM UPI pay… N try 2 time.. But agin same i got 2 msg of transactions from BHIM UPi that payment is done but thier machine said that transaction is failed…so instead of 260 rs i got deduction of 780rs from mamy Google pay and BHIM UPI contacted Bank account…so whrn i told the manager he told me that u will get refund from 7 days..but now 20 days past no refund
