Two-thirds (67%) of British adults, equivalent to 32 million people, say they have received an unwanted telephone call, text, email or letter about PPI, according to the figures from Citizens Advice Bureau.
Of these, 98% did not feel they had given permission to be contacted in this way, and more than half (55%) estimate they were contacted more than 10 times in the past 12-months.
The organisation found people's work, family time and household chores were being put on hold to answer calls about re-claiming PPI.
One-in-four people (27%) received their most recent call during a family meal, while around one-in-seven (14%) received the call at work, including during meetings and presentations.
Phone calls (91%), automated messages to landlines (39%) and texts to mobiles (35%) were the most common ways people were contacted about PPI claims.
The new figures are from a national survey of 5682 people aged 18 and over in Britain, carried out by Ipsos Mori in June and July.
Citizens Advice research, released in May, found 56% of complaints about PPI claims management stemmed from cold calls.
Gillian Guy, chief executive at Citizens Advice, is calling on financial services firms to be banned from cold calling and said: "I want financial services firms to be banned from cold calling. That will help consumers identify good firms from the bad. Then if you get a cold call you'll know it is either a bogus firm or company not to be trusted."
