ID Mobile, Three and Vodafone named worst telecoms providers by Ofcom

ID Mobile, Three and Vodafone have been named by telecoms regulator Ofcom as the worst providers for customer service, in its latest report on complaints in the telecoms sector covering October to December of 2020.

Ofcom uses a combination of interviews with customers and information given by providers to produce its league table of results. While complaints about pay-monthly mobile had dropped overall, complaints about broadband services had increased.

The findings support our research that shows that some providers simply don’t stack up when it comes to customer service, reliability and value for money.
