Hollard incompetence

I have a funeral cover with hollard for 5 years and i am due for my cash back benefit.i never thought it would be such a hussle to get wats due to me .in june i phoned hollard to ask wen am i getting the money the consultant checked and said its been processed it will b in my account within 5to7 working days weeks passed and i phoned again and i was put on hold for more than 20 minutes and then the phone was cut off.i phoned again after a week and then a consultant told me they overpaid other clients so i must be patient i will get the money in a few days.the following day i was sent an sms saying they want to know if my issue was resolved and when i open the sms it was the review asking for rating i waited a few weeks the money was not in and then i phoned again and then i was put on hold for 30minutes and then the phone was cut off im really dissapointed in this company ive never missed a payment but they treat me like trash i really thought it was a trustworthy company but i was dead wrong.i just want my cash back and leave them,its funny month end deduction are never a hustle but when a customer is due to get whats entitled and earned its a stress cant wait to cut ties with such incompetence
