Capitec wants to **** me

I am really disappointed and I will take this to the ombudsman. I called on Friday 28 August and asked the call center agent to please move my loan repayment date from the 25th of every month to the last day of the month as the company I work for has now changed our pay date permanently. I did the change in April but I saw it was not changed, I even emailed them the letter from work as proof. To my surprise the girl says she will change it but my loan term will extend by 2 months. I was shocked and asked her why? She said she doesnt know the system is just telling her that. I then said listen I want my installment to stay the same and all I want is the date to be changed and she insisted it will extend by two months. I am utterly disgusted and shocked at hom capitec is ripping me off. I never missed a payment, I never asked for a payment holiday yet my loan gets extended by two month for *******. I will be contacting legalwise so they can contact the ombudsman for me because it simply does not make sense at all
