Spectranet — refund on cancellation of spectranet connection

Sir,
I am an old customer of spectranet. I shifted my residence to sarajapur in bangalore where spectranet had not established itself. After a year or so spectranet reached my area of residence. On their advertisement, i opted for new connection at a cost of rs. 6587/-. They promised to install the connection within two days. Verification was done but no one came to install the connection. On enquiry, they said that by end of day it would be done but nothing happened. This went on for almost 10 days. I had asked my current internet provider to de-activate. Thereby i was without internet for almost a week.in view of this, i cancelled the connection and requested for refund. They said that the issue has been taken up and within 30 days they would refund the amount. It is more than one and half month, refund has not been made. I got a mail saying that the issue has been resolved. Can some one explain.
