Cash back due

After 6 years boniyas my loyalty with Bonitas im totaly unsatisfied with the service. I called customer care four time regading cash back im dure this month but no one had an idea. All the consultants ive spoken to promised to send me documents for me to sing before cash back can be paid.. To thos day im still waiting. Im so dispointed after so long with you an never skipped one premium and this is how you thank me.... Im angry and dispointed becase to me ut like you dont want to give whats mine.... One consultant by the name of neo droped the line on me while i asked to wait on the line while still waiting for docs..
