Ccavenue — payment considered high-risk

I have been trying to contact ccavenue on [protected]@ccavenue.com as they have pointed my transaction as fraud or high-risk because of address issue. So my hosting provide company to whom i paid through ccavenue has suspended my account. Hosting company said that it only start if ccavenue told them and this ccavenue don't have time to reply you back. It's been more than 7 days and i don't heard back from them. Third grade service from highly reputed company.
