Yoco has Terrible slow service

Really poor service!!! We did a refund back to a client from our card facilities and after a month they still wait for their cash back. Everytime we call the Yoco Hepline or send an email you have to litterally send multiple emails to get them to read your mail.... they only reply with automated emails and never call us bac to keep us up to date with our problem..... sadly disappointing service!!!!!!
