I made a purchase with sinhagiri.lk with good faith and ended up being charged full payment instead of instalment plan for 12 months, which provided by NTB on behalf of AMEX? AMEX is known worldwide and a bank I never had an issue with for last 8 years but used only once with SRI LANKAN bank and had plentiful for life. When raised the issue to merchant they admitted that I have made purchase correctly for instalment plan 12 months but payment proceed in full in an error ?? that was a month ago, since then SINHAGIRI passing ball to NTB and NTB pass it back to SINHAGIRI for a month and said there s nothing they can do. Then why did they took full payment ? Did nt they aware of how AMEX work ? Because of their error why would customer suffer and losing money? NTB *** told that I made payment purposely to take advantage ? *** I have been chasing my *** off to get this sorted wasting my time just because of their error. Never trust this bank or Sinhagiri.lk both doesnt know how their system works or look after their customers just ripping off whenever they can plus when an issue arises passing it to here and there never bothered to solve it in timely manner. I am a person already disappointed with Sri Lankan fxxx banks and their service and thank you for refreshing that disgusting experience again. Safraz Ra**** @ NTB thank you for being useless and a pain in the *** you are good at not taking care of customers and being a ****head. Nirosha @ Sinhagiri you are painless piece of **** I wish you both very bad future and stop ripping off people unlike you we all are making money out of our hard work not just sitting and emailing once a day !! I would never ever use Nations fxxx no trust bank or Sinhagiri ever !!
