Confused bank

So I been with capitec for years, I have a access facility with them, I have 14months left to pay off what I need to, for the past week I have been trying to take out of my access facility to make a purchase, but it only gives me the option to pay back now in a min of 35 months and a max of 35 months, so it's a pain, cause weather I try to take a R10, R100 or R1000 it only has that option of 35 months, if I take R10 how can I pay R10 off in 35 months, my wife tried on her phone she only has the option of 36 months, and yet she hasn't even taken a cent of her access facility, when I explain the app has an issue, I get told the app working fine, so can someone at Capitec who knows *** is going on resolve this and get back to me please, cause now time is being wasted.
