MTN sild me dreams

I have not even got any feed back as to MTN deleting my details on their old system and I had advised that I am trying to build up my credit score however no one is even contacting me in any form I have to make a follow up each and every day and instead I get all the automated responses from them and really this is frustrating as I have tried sending emails, messages via Facebook messenger, even went to an extent of writing a review on twitter but still I haven't got any solid feed except from them advising that hey will delete my information but they just gave me false hopes and sold me dreams.
