Jiomart — No refund/no resolution

I had ordered 2quantity of wagh bakri leaf tea of 1kg each on[protected] and on[protected] i got a call from jio confirmation dept team asking me whether i have canceled the order i said no i have not then soon after that jio delivery agent called me and said he himself has canceled the order bcoz order was incomplete means he had only 1kg of wagh bakri tea not 2kg so he canceled it soon after i called customer care explained him everything customer care told me to take 1kg and he will raise a complain regarding the same and refund will be issued against the missing 1kg wagh bakri leaf tea then i called up delivery agent and collected 1kg leaf tea. But till now more then 2months have gone bye despite of multiple complains, mails they have not refunded the amount of missing 1kg wagh bakri leaf tea amount they just say we are sorry mistake happened from backend team we will give you resolution soon but of no use they are useless
