Idea Postpaid Connection - Mumbai` — Sim blocked

Hi my name is Naveen Jain S L, I had taken an Idea postpaid connection 16th of January 2009 from there franchise My Mobile in Irla, Vile Parle West. But after few days i.e., 4 days my outgoing were barred and subsequently next day my incoming also were bloced, i.e, my screen showed "SIM card registration failed". On enquiring about it I was said that my verification was done twice and it was negative, were as the verification was done only once and that too I didn't find any thing to be negative in that. When I spoke to a customer care executive he promised me that the re-verification would be done on 20th Jauary 2009 between 4P.M to 6 P.M.. I waited leaving all my other work to attend the verification in person, but no one turned up. When I went to the franchisee, the next day i.e., on 21st the executive promised to get it done by the evening, even that didn't happen this made me feel paralysed as my outgoing and incoming both were blocked as I had given my contact number to many of them. Please advice me how to go about it.
