False adverti*****t.*********** service

I was a client of Absa idirect insurance had cashback . When I was supposed to get my cashback Absa took me from pillar to post .I was told it takes 30 days for me to get cash back when I called and that was in May .today we are in June towards the end still no cash back,no feedback I tried to call bit was transferred from one dept to the other till my R110 airtime was finished . I am truly disappointed at this company.After such loyalty 6 years and no claim was submitted premiums paid religiously . I wonder why were they promising cash back voucher when they are not going to give back. Today no one is even calling to apologise or explain .what kind of company is this
