LET DOWN SINCE 2016 - DISGUSTING!!!!

I am honestly so disgusted with the service ive been getting since i joined momentum in 2016. Last month we requested to update the banking details as our company changed the name as well as the banking details, it was going back and forth because Momentum cant ask for the correct documents and requirements all at once but once you submit something then they come back requesting for something else, anyway after all this disappointment we received confirmation that the banking details has been updated accordingly and that the payments will go off from the new account. End of July comes and Mometum deducts 1 amount from the correct "new" account and two payments from the old account (wrong) !!! When i contacted Momentum to find out whats going on and why are they debiting from the wrong account , i get told that we didnt ask to change the banking details for the healthsaver and the multiply ....i mean this is common sense ... why would we only change one debit order to go off from a different account... Momentum is just being so useless and *********** and leaving me with a bad taste in my mouth time and time again.. I am in the process of getting medical aid from a different health provider so i dont have to be disgusted everytime i have to deal with momentum! Same goes for claims , there is always and issue when t comes to claims... when i submit claims and ask for the refund to be paid from my healthsaver then momentum does completely the opposite as if they are trying to be spiteful because they put a code and say : "member not liable", however i already PAID and trying to claim back from my HEALTHSAVER which i am paying but then they dont refund me!!!!ONLY after a complain and have to WHATSAPP them to ask them whats going on , then only will the refund me my FULL amount... This happens every time!!!!!!! and thats why i am so sick and tired of this AWFUL experience ive been having since i joined MOMENTUM in 2016.... but i cant wait to leave MOMENTUM as my HEALTHPROVIDER!!!!
