Martin Bamford, of IFA Informed Choice, said the Claims Advisory Group called him several times on his mobile phone offering cash compensation on the assumption he was mis-sold PPI.
It said it charged a fee of 39% of the value of the settlement on a no-win, no-fee basis.
Bamford rejected the call and has now written to the MoJ arguing the firm’s tactics are unfair on members of the public who may not know they do not need the services of a claims manager to secure PPI compensation.
“My fear is many people who receive these calls will not realise they do not need the assistance of a claims management firm if they have been miss-sold PPI,” he said in the letter.
“I understand Claims Advisory Group is regulated by the Ministry of Justice and your rules prohibit unsolicited cold calling.”
On its website, Claims Advisory Group says: “There are more than 35 million PPI policies in existence in the UK and it is believed many of these may have been mis-sold. [We] can help people like you reclaim what is rightfully yours.”
Its says successful clients have claimed back an average refund of £1,876.
Claims Advisory Group was unavailable for comment when contacted.
People who have been subject to PPI mis-selling should firstly contact their bank and, if the claim is rejected, take the case to the FOS.
