Microsoft — Surface Pro 7

Company has been requested to repair or replace a unit. There have been 100+ emails to the company outsourced customer service and no one is replying. Once a return label to ship the unit was sent but the company chosen by microsoft to ship the unit is not serving in india domestically. So i am stuck, i have asked them to choose or accept other carrier but they haven't been replying.in the meanwhile, another part of the product has stopped working. Microsoft needs to fix this, they do not have a contact email for india and continue to serve poorly.
