Extremely unsatisfactory service

Iv been trying to contact discovery health to sort out my app since June and I have had no help .my cover has now been suspended,they say I must pay before they sort out the problem with me logging into my app..the app was not working long before my account was suspended so it makes no sense..I cannot get hold of your call center I keep getting sent from pillar to post.. please can someone phone me so I can pay my arrears and fix the app
