As of January 16, 2011 my debt before the Bank was circa 42600 RUR (circa 1000 EURO). I decided to settle it as of the same date via Citibank ATM at Aviamotornaya office of the Bank. The amount of 43000 RUR (8 notes*5000 RUR and 3 notes*1000 RUR) was inserted into the slot of ATM, counted and ATM displayed 43000 RUR asking if I confirm the operation. However after the confirmation the ATM suddenly returned 5000 RUR and credited account just for 18000 RUR which means that 20000 RUR disappeared!!!
As it was Sunday I contacted Bank’s on-line service to file my claim for investigation. As of January 20, 2011 the Bank informed me that they carried out an investigation and no extra money was found. So I understand it in the way that they did not care to check ATM's register to find out the real reasons.
IMHO, it is outrageous that such things can happen nowadays and people like me have great difficulty to prove anything in such situations. I am sure that a kind of criminal activity is going on in the/near the Bank, so the Bank should pay strictest attention to this case.
