CELLPHONE INSURANCE, STILL PAYING FOR CLAIMED PHONE AND DIFFERENT DEBIT ORDERS

i had claim for my lost phone IPHONE 5S and they gave me SAMSUNG A7plus which i was paying R175.00 after that they debited R255.00, I called and asked why was I wasn't notified about debit order changing they said its for SAMSUNG A7plus "BUT THEY ARE SAME VALUE". I went to insure 2 phones for my children SAMSUNG A2 core and Huawei Y5lite they Only debit for only one phone Y5lite, i also called and told them that they must debit for A2 core they also told me that i should confirm my banking details one number was wrong and I was still paying for IPHONE 5S i told Sheree to cancel IPHONE 5S as it does not exist anymore she told that I will be paying R66 each for all my 3 phone which is R66 Samsung A2core, Huawei Y5lite and Samsung A7 plus, but to my surprise they debited R66.00 and R175.00, how many cellphone insurance registered with finrite and how much should i pay for as debit orders change every now and then. i am insured for SAMSUNG A7 plus, SAMSUNG A2 core and Huawei Y5lite.
