The TMA, an independent, non-profit organisation initiated by Data Locator Group last month, claims to have up to 10 founding members. Its initial aim is to lobby for a complete review of the Telephone Preference Service (TPS), which currently stands at more than nine million consumer registrations.
James Kelly, DMA managing director, said: "I welcome the contributions of anyone who can add to the constant attempts of the DMA to protect the industry, but I'm not sure what they believe they will achieve.
"Time is better spent tackling the cause of TPS registrations - not the symptoms," he added, citing the abuse of technology leading to silent calls as one issue.
In its own call centre survey of 2,000 TPS registrants, Data Locator found that 65 per cent still received sales calls.
Richard Webster, steering party chairman of the TMA and group data director at Data Locator Group, said this must be scrutinised.
"Many of these are overseas calls. This highlights one of the points we are making. The aim of the TMA is to look at this and try to ensure customers receive value for money."
