I signed up for the trial period but the app was not suitable for me I cancelled within the trial period and received an email from PDF Master confirming my cancellation and saying that no further monies would be deducted, however on checking my account they had deducted the monthly fee, I have sent several emails to their so called customer support service asking for a refund or an explanation and they have just totally ignored all correspondence, I would urge anyone considering signing up with this ignorant unprofessional company to avoid them completely there are other companies that offer much more competent professional services.
