I decided to share this info with you all...
...in case anyone that uses Airtel network in Nigeria is reading this and is not yet aware, Airtel Nigeria now has a whatsapp number for swift response to complaints and other issues. The number is:
0701 0000119.
Please, endeavor to share this info and let others know. Some of my several numbers (both personal and company numbers) happen to be airtel and I've already been using this their whatsapp number for some time and they responded to me. So, you'll do well to tell others. Cheers!
