They called me to offer me a reduction of interest on a debt of $ 167 thousand pesos, we made a plan of 3 payments of 21 thousand pesos to settle the debt, finished + a start of the plan in advance of 7 thousand pesos, they deducted all my payments of the debt but never finish it
I tried to contact the advisor who followed the portfolio and he stopped answering me after several claims made, accusing that the bank is behind in the reports, I contact the bank and they are up to date with the reports.
I try to communicate with the offices and they never attend the advisor does not attend.
several people have the same problem and make the report.
do not pay, the plan they offer does not end the debt
