My name is naresh kumar gupta and my number is [protected]. I have applied mnp from aircel on 22nd feb 2018 and paid rs. 300 for the same. I have receipt for the same. Then after rigrous follow up again some o[censored]r person came to my officeon 9th march 2018 and took all the proofs again with my finger prints and handed over new sim and told it will get activated in 3 days. But still now nothing has happened. Is this the service u provide to ur new customers. I think u should sort it and help me out in this case.
