Waiting period waiver

I opened Funeral Policy with Capitec 2020, then 2021 i took another policy and while i have the other policy. then went to the bank to cancel the previous one of 2020, but they decided to refund me. now my problem is if i took the cover and i cancelled or other one lapsed why must i start waiting period from scratch? according to clause 7 sub 7.7.2 this is not they telling me now. the proof is there and they still refuse to amend my waiting period. if the proof is there why cant they amend my waiting period when they have waiting period waiver that states that within 30 days the other policy must be cancelled or lapsed????????
