Unpleasant findings regarding the long term loan

I took a loan in this bank on 1 October 212,it was a 78 months loan, and on February 2019 I went to the branch at umlazi mega city, to find out when will my loan end because I've been paying,one of the consultant told me that March 2019 will be my last instalment ,and then on April 2019,the debit order went through and I did a reversal, and in may same thing happened on the 15th so I did another reversal, then I went to the bank again because I was getting the phone calls from Capitec consultants,saying im in arrears,so I went to the bank to find out what is happening,they did not help but instead they called head office and I spoke to the lady called Patience she was so rude at first,she did not want to hear my side she kept on telling me that im in arrears of which I was confused as to how come im in arrears,because I have been paying my account every month,she told the guy who was a Capitec consultant to print the statement for me and that I need to pay this money ,this lady by the name of Patience she was very rude, and that is where I lost it I told her that I will not take the statement that the consultant will be printing , I will take matter to social media so that people can be aware that Capitec is robbing ,people,because now every time when the consultants from Capitec were calling me they were telling me I was in arrears,At first it was R4842.55 and when I asked now when will this loan be paid up,they told me the end month will be May 2019 that was in 7 June 2019,and on 19 June 2019 they called me again and sending messages and now they had the diffrerent date which was July 2019and I'm now owing R7205.44, and as I was talking to Patience ,I did explain this ,bt she kept in telling me that I have to pay the money,which money because now every time when somebody from Capitec calls me they will have a different amount to the one that i know and the different date,so the Patience because now I told her about social media and that is when she started to listen to me and she told me that,she will take this matter to the complaint department,I must wait for their calls. And the on June the debit order went through again After 3 days another consultant called Jodie Sampson called me telling. Me that they did the investigationnl and they find out that on my 2013 I changed the date of payment,that is why I'm in arrears,and I asked her about this different amount that I've been getting messages for and these different dates ,that where she told me to ignore those amounts,it was a mistake ,I'm not using Capitec bank,by I do have the saving account if I want save some money for myself ,and I saw message that my money that was in my saving account was taken out, then I went to the Umlazi mega city branch again for reversal,the poor service i got from that branch,they told me that they can't help me l,and they can't get hold of Credits department bt they will not reverse the money that was taken out on my account because the system shows that I'm in arrears,bt I sat there and I told them that I'm not leaving until they did a reversal,yhooooo the attitude that they gave me l,left me in the desk,they continued with their business as if I did not exist,I was humilliated,angry but there was nothing I can do because I needed that money, after 2 hours the branch manager came to me,with an arrogant behaviour telling me that they won't do a reversal and it not their problem so if have a problem I must take this matter to OMBUDSMAN for banking ,bt according g to their side there is nothing they can do.and I asked this branch manager about the R 7205,she also said she doesn't know about it,and I told her that if was not checking my balance every year which means that ,id still be paying the loan that was supposse to end in March,because now it is isJune and everytime I deposit the money into my Capitec account ,it goes through to this loan,the loan that does not end,the loan was for 78 months and if I'm doing my calculations ,the 78th month was March bt this calls that I'm getting they now telling that the 78th month will be in July.
