still paying for suspended contact

As a long standing customer with Cell C,i regularly take a new contacts with them. I passably had 6 contacts with CellC this far,from BBM Z to Sony and samsung and now Huawei, i have lost some of these phone over the years and usaual Cell c helped me by getting up and running with a new contact asap which was always great,recently i descoverd that i have been paying for a sim card that was temporally suspended for the last 3 and a half years,when i lost the BBz,they gave me a new contact and never cancelled the old contact making me a loyal customer pay for another 3 yaers for something i never got to use,since all of my interaction with CellC they never bother to tell me that i have a temporary suspended sim card,thus making all the people i interacted with ***** or either incompatant to help a customer so i got another call from sale and then again i was told only 2 contacts but then i call in again then i only get told ah 3 contacts - just refund me for your incompatence and i may decide to remain as your customer - oh you dont care of only one customer cancelling - if you want me to take this further from here i am willing to do it because your processes and help was blatantly just theft and now you just want to blame the customer,if some says the thing is lost or stole it is your responsibility as a company to know what to do to help me,if its a new sim or whatever,but you gave me a new contact and just left the other one for me to pay,this is so unfair and i am sure the courts will see it my way.so prepare for a law suit or credit me for what i could not use due to your company incompetence.get a decision maker that is able to deal with this asap. ref ********** ********** 51 and ********** ********** 67 - here is reffrence to my issues when your agents says 2 contacts then when i call back then you see 3 contacts the incompetence.
