I need solution

I'm very disappointed with this store I have an account with them but my balance was R0.00 then after 6 months my balance was R94.00 I went to the store to ask they told me it's airtime subscription and I've never buy any airtime in this store and I will never do that stupid thing. The promised to investigate later I got a call from their call center they told me that they have sorted it they reversed that amount because now it was already R164 . Suddenly I was called by the lawyers about Edgars account what's a problem with this store Another problem with same store my wife also have account with them , she's being paying installment since 2016 this year July she asked them for balance then she paid them the whole balance. After 2 months she was also called to come and pay account then she went to the store to find out what's going on (chris hani mall vosloorus). She was told about funeral policies that she never signs for them, she asked for documents she signed they promised her to wait for investigations then later they said only 2 policies can be reversed into her account and we asked for documents and the other policies but still now this is not solved. The amount of R19000 when we count the money they were taking since 2016 till now
