Sureswipe / ADUMO credit card system penalties.

Sureswipe / Adumo provided credit card payment services to our business since 2015. Initially under Sureswipe, their service was good and they provided very low interest rates on card credit and debit card transactions. From the time they became ADUMO, their service is extremely poor, they charge irresponsible and irrational penalties and change the signed agreement however they choose to suite their needs. When queried regarding the extra charges they offer rebates but add charges and imply the agreement has changed. Customer services have no idea what a customer is. I recommend that any business using Sureswipe / ADUMO credit card system critically review their agreements and contracts and ensure that their billing is correct and review their services, costs and penalties. I am in dispute, and intend going to the Ombudsman.
