Has anyone being getting this really annoying and persistent calls from 08020000000?

I get different names all claiming to work for Airtel.

And the line they all tow is really very irritating.

Imagine Airtel calling me to inform me about some offer where I get 1500 for 300 of my airtime credits. And they even go ahead to ask if they should deduct the amount from my Airtel account.

I can only imagine - since when did Airtel start calling to inform subscribers about offers. Even the plan I'm on gives me way more than 1500.
