bad service from consultants not putting clients first

i am beyond aggravated and angry with the service i received from discovery health. they called last month informing me my membership will be withdrawn on the 30th of June and i informed them i will continue on my capacity. i was informed after speaking to a lady sibongile for a good 1 hour i wouldnt be able to upgrade my plan. ok fine i agreed we continue with my existing plan. they called again and told me i owe 378 from a membership in 2018. i paid it. today i find out they did new application instead of my plan continuing and today i am told i must fill in documents 3 weeks later. my debit is meant to go off and i have a gynae appointment for my prenatal preg tomo and today im told debit is not going off and i dont have cover as if its my fault for their incompetence. i need my cover active today and i need debit to go off today
