Sinch: Fraud Support Experience (Case Study)

Sinch are a company located in Stockholm, Sweden that own Inteliquent, a reseller for VOIP services.

Based on personal experience, their customer support in regards to reporting fraud, via direct email or through their abuse report web forms, has been very poor. Neither Sinch or its wholesalers provide the consumer with updates for any of the cases that are submitted through their webform, which can be found here: https://www.sinch.com/legal/report-scams-fraud/

What usually happens is, one will get a confirmation email from Sinch that the report has been accepted and has been forwarded to the wholesaler in question, but no further updates are ever provided to the consumer about their cases.

Often we have found that the numbers remain live after multiple reports. If a number is taken down for fraud, one must call to verify it as Sinch does not not update the consumer at any point during the investigation process, making it difficult for us to say for certain if either Sinch or its wholesalers have acted upon consumer reports.

This post will catalogue every number on the Sinch network along with its wholesalers that are or were used to facilitate phone scams.



The info was blacked out because the numbers were ditched by the scammers after sharing them on scammer.info
