highly unprofessional service

I just recently joined discovery health and spoke to one of their consultants telephonic-ally his name is Sam Moloisane, when sam called me i specifically asked him if my debit order can go off on the first of march reason being is i has previous cover that i had cancelled and need to make 1 last payment for. I also asked Sam will i be covered immediately to which he stated YES! moving on.. later that month which was 1st of feb discovery debited my account, i called in tried to speak to Sam to no avail until he called me and assured me that he has sorted everything out and my cover is available and payment will go off as discussed on 1 March. Yesterday i received a suspension letter from discovery due to non payment, again i call in ask for sam again his not available, i sent emails to which he never responds to. I had to then speak to someone else who assisted me, right now i have no cover and this is all Sams fault, had he been honest from day 1 i would of had a back up plan in place!!
