Cakedecosupplies review for Chargly ‑ Collect POS Fees

Unreliable app, Constance issues with this either it works and charges on some transactions then through out the day does not work to charge the fee when we click on the button. Then if it decides to charge it calculates the incorrect amount eg. $900.00 charged .19c credit card fee! Should be $16.65. This app has incurred by business to absorb excessive card fees. Still No support or response to fix this issue, i have been charged a Monthly fee US$5.99 for service that does not work and has cost my business ridiculous amounts of card fees that has not been past to the customer.
