Legal wise

It was round about March when I phone to Legal wise wanted to change my banking details they told me that my account has lapsed and it was only 2 payments that I missed it was November and February and they said they did send the notification which they didn't, different consultants told me different months that my account lapsed, I called the head office and told me to pay R 180 for those 2 payments I did and on the other side I opened another account while I was busy sorting out the lapsed one from june they didn't deduct when I call they also said it has lapsed also while i was busy making payments consultant told me he will call me back and till today I've being waiting. When I call the consultant that was busy with my account she told me that their down with a system till today I'm not getting any respond, very disappointing such a huge company with such a bad service. Being paying them from 2015.pls help
