bad service after my husband death

on the 19th of December 2017 my Husband Trevor Pillay passed away after a long term illness we took out a policy for over 10 years now with sanlam and the policy covers DEATH ,DREAD DISEASE AND DISABILITY about 7 years ago we claimed for our disability policy as he was unable to work and Sanlan did pay it off ,when my Husband passed away i did go Sanlan to claim my Death policy a lady there did assiste and say there was a policy on death and it will be paid out and asked me for my husband details which i did give her but after 2 weeks i went back to Sanlam to ask why this policy is taking so long to be paid out and there did advise me that the policy had been lapsed after the disability policy had been paid out which was over 7 years ago but i don't understand how that can happen as the policy was a whole in one policy and for 7 years i never got a letter from Sanlam stating that the policy is lapsed which dose not make any sense to me i have contacted my lawyers and there did advise me that i have a strong case against Sanlam as the only reason there may have done this is because after we claimed for the disability cover there realised that very soon we will claim for the Death cover so there stopped the policy without advising us there also advised me to get a hold of of Sanlam and if there do not help i should take it further i need this to be paid out soon it is very costly to have a funeral and i am the one left to deal with all of this please someone help thank ,my contact number is **********
