Tasc Outsourcing review: job loss takaful charges

Dear Sir,
whomsoever reading this message please respond and please suggest me to help as I have an account in Dubai Islamic Bank. I had opened this account 2 years ago and i was promised by the sales and service representative that AED 8 would be deducted for Job loss takaful charges, once if i lose my job i would be reimbursed and entitled for an insurance coverage of AED 30000, as i lost my job on 13th July 2017, i went to claim my amount as they refused to pay my amount and said that I would only be entitled for AED 4000 which is not acceptable and not really pardonable and i really want to solve this issue. please help me
