Airtel — Sim not wahala

I registered a sim on the 5th August 2022 with one of your branches here abuja. On the 7th of same month i recharged 20GB data which i used for just 4days. 6 days after acquiring the sim, it started showing registration failure.
I have been to office where i got the sim countless times to resolve it but to no avail. Called customer care to which the attendant as at the time said withing 48hrs and it will be resolved. I called back after 48hrs and a customercare attendant said the sim is active from his end but not mine and he doesnt know why.
I sent an email to [protected]@ng.airtel.com and one Abigail Omojola replied with the issue has been sent to the appropriate network department. It's been 29hrs and no update.
