Total incompetency and negligence of Vitality "support"

Discovery and Vitality, overall, quite a good company. However, not in support aspect. So-called consultants demonstrate total incompetency and negligence. Issues closed without resolution or attempts to contact me. Rare answers provided have nothing to do with questions raised. Example - ***. At some stage, I couldn't had Debits orders processed from account for Apple Watch. I've contacted vitality to pay outstanding balance - no reply, nothing. Then my account was handed over to collector - again, without any notifications or attempts to contact me.. I've sorted it with them and trying to rectify with vitality - no response, no calls and the only reply I've got had nothing to do with my request..
