ipayDNA kept funds, rolling reserve, claiming the bank was the one holding the money miami, Internet

we have been going about this for almost 2 years, first the wouldnt pay the invoices and we had to stop processing with them in order to get paid, payments were delayed for more than 3 months, when this happened company decided to start decreasing the volume 'cause it was obvious there was something iffy going, then when the time came to pay the rolling reserve the excuses started coming and they never paid the money, after about 8 months they decided to settle the amount paying and amount on a monthly basis until the complete amount was paid in full, however, as usual with this company, they made 2 payments and that was it, now they say they will not honor the agreement, so i warn anybody thinking about doin biz with them
