Mbd is harassing me for Vodacom account I don't have.

I have been getting Vodacom email statements for someone. For the past few weeks I got calls from the Mbd attorneys to say I must pay my Vodacom account, I told the lady that I don't have a vodacom account. I asked her to give me their email address so that I can send them the statements I 've been receiving. I currently have a contract only with Cell C for data and My Fnb prepaid simcards. I am tired to be harassed by attorneys for an account that I closed some years back. I hope this is not on my credit report because I promise it won't end up just like this. Can you please explain to me what is happening because according to the lady who called me the account was opened in Limpopo and I left in 2015 and by then I think my account was closed. Can you please ask Mbd to be sure with their story, why do i only have to find out only this year about Vodacom account that the lady from Mbd claim it was opened in 2016?For 4 years why didn't I get call from Vodacom because I used to be their client? If you send me an email adress I will send you statements that I 've been receiving from Vodacom and I will take the matter further for sharing somebody personal details with a stranger. I know vodacom is aware of POPI (protection of personal information) also this client won't be happy that you are sharing his information with a total stranger. This is the matter that will be of interest to ICASA.
