Consumer Redressal

i recently purchased a phone online and recd. a damaged product. on complaining a prompt replacement was sent. the said replacement is a faulty piece itself and now although i am covered under the guarantee to get it replaced by the online seller within 30 days, my calls and requests have been intentionally delayed by the service personnel and as of date i am stuck with the faulty product and rs. 13000 lighter wallet. the company is sly in following its duties towards the customer as it calls for split seconds and cuts the line before one can answer the call and then sends a message that reads that the problem is either solved between buyer and seller or that the buyer is unavailable for compliance procedures. this is ugly and i am flabbergasted. I feel duped and wish that the govt. steps in to regulate this. but before all this i want justice and my money refunded or a suitable replacement sent along with appropriate damages to fill in for the time spent and harassment faced
