For last 3 months i am visiting airter center for post to pre migration. But till date it is not done

Initially visited sanpada to give req. The center closed in two days

Then i had visited vashi airtel center for post to pre migration last month wen my bill generated on 9th oct. Airtel executive asked me to visit on 15thoct and wen i visited on 15th they said they can only do this online on 9th and tried to change plan. And reduced my free mins and also did not add the data plan.
And asked to visit 9th nov. Now i hve visited thrice, either they say server is down, bill is not updted nd directng to anoter airtel branch

And the server remains down in their chembur branch

Most pathetic service experience i had with airtel

Neither they have waived off extra charges.. And nor migrated.

I would prefer to switch my no. To idea
