OUTSTANDING EDGARS ACCOUNT

My personal Edgars account have been settled in 2013/04 and I have a letter from another institution that this account have been settled. R&T Attorneys started sending me sms's since 2015/08 stating that I have and outstanding Edgars accout of R7000, I did phone them to explain that this is indeed not the case and I forwarded them the settlement letter to proof my statement, but still I keep on receiving the same sms's and they do not stop, Thabo that is working there did indeed told me the first time I phoned them in August 2015 that my name must be removed from their systems, but still they keep harrassing me, this is getting unbearable and for me not acceptable as this is my name they are playing with. I did also report this to my Attorney and asked for their assistance. if this was the case where were they in 2013/05 up to 2015/07 and my account number differs from theirs! This Company is clearly taking chances!!!!!
