No resolution on service request

<p>I took out a contract about a month a half ago. The phone was delivered and I asked to exercise the cool off period right and I returned the phone to the nearest store as instructed by the call center agent. I was told I would be sent an statement of usage for the 5 days I had the phone so I can pay for the airtime and the data I used. I have called and email many times rrequesting the statement and it has not been sent to me and now my line is blocked for non payment and I cannot do anything with my line. I have been called by the collections department demanding outstanding payment and I have told them I cancelled the contract and the phone us returned and I am waiting for the statement to be sent to me and still today the statement has not been sent despite having called the call center numerous times and emailed the sales agent to follow up and there has been no assistance,</p>
