Pathetic service paying for an unknown policy

we have taken up polices for our children and have paid for the past 5 years. We made numerous attempts to contact Momentum for the policy documents , guess what , we taking your money but can't find your policy. Spoke to numerous brokers who promised the world but nothing has been fruitful. I refuse to pay the policy until someone can provide me with the correct information. Kindly contact me urgently to resolve. We took the policy/ investment in 2010 and its 2015 now COME ON do you guys know what you doing , the premiums increased but we have no information on the policy TOTALLY UNACCEPTABLE. I WANT ALL MY PREMIUMS PAID OIVER THE 5 YEARS REFUNDED ASAP
