Trying the same scan after 2 years

I was just contacted by a very rude customer consultant for MBD Attorneys saying I owe R1908 on my Virgin Active account. I do not, nor have I ever had an account with Virgin Active. My deceased mother had an account over 15 years ago which was closed and paid in full. In April 2013 MBD Attorneys contacted me with the same **** and after many back and forths, I was assured by Zukiswa Mholbo from Legal that my file was closed, that there was an error. This was after I said I would be reporting MBD attorneys to the LSSA. I didn't proceed because I took in good faith that the error was rectified. I still have all the correspondence from 2013. Now 2 years later they try the same ****! I am going to report MBD Attorneys to the LSSA and see my lawyer about making a case against them. I don't know how many people they fool on a daily basis but I am not one of them. How disgraceful!
