I have a health plan protector with Discovery Life. When Discovery phoned me over a year ago to sell me the plan, they used a sales pitch that I will get money back on a yearly basis. I have this plan for over a year now and I phoned them on the 21st of May 2015 wanting to know what the situation is regarding the funds I must get back and all they did was sending me my policy documents that I already have. Since my 1st phone call, I have phoned a couple of times and event spoke to a supervisor that said to me h? will sort it out and till today they have not come back to me regarding this mater. To top it all of, they put a debit order on my account twice on the same day. They are quick to take your money but when you enquire about the money you must get back, you get no answers and no one is willing to sort out your problem
