I have to pay for something I cant use

I logged a complaint a week ago about two mtn sim cards i can not use. A consultant told me I must go into a branch and do sim swops i did that today and still it says check operator services. And now I have to pay for the s
swops. I will not pay for them and I am gonna stop my debit order untill nashua fixes my problem. My id is 8311240028087
