Firstly, we must understand that TrueCaller is an independent entity and Exotel has no control over its business. TrueCaller's users mark the numbers as Spam and they save the numbers as they wish. If you observe the loop, Exotel has no role to play here and as a result, we cannot unspam a number or change the name. However, we offer a solution for this. Please reach out to our Customer Happiness Team or your account manager on the following contact details to know more about this.
