Rectification of personal details

On the 06-02-2015 I went to rectify my Surname from Mahlango to Mahlangu I went the whole through the process of ID application paid R70.00 was told I will receive an SMS once ready. which I never did, and went to check in September without that SMS. I was sent to counter 8 was told to Pay R70.00 to get a confirmation letter. I returned home cause I had no money with me. on 24/03/2016 I went and paid the R70.00 got the letter on the 29/03/2016 but was told I am not going to get the ID document. I must go and do an application for the Smart card and pay R140 which I don't have a problem doing but the question is the processed I did fingerprint taken, ID pictures and the R70 paid what was it for, I never got an answer, called the Head quarters *** spoke to Lindiwe Nkadimeng who couldn't help me but referred me back to Randburg. Tried calling the Office manager Herman who is forever in the meeting every time I call. Sent an email to Herman no reply as to date. According to Lindiwe Rectification is only R70 , also confirmed that on the website. So what happened to the first R70.00 I paid what was it for?
