NO CASHBACKS NO MATTER WHAT

No cash backs paid for absolutely no reason. i changed my bank account number at the beginning of this year. i notified both Discovery and Vitality accordingly. they acknowledged receipt of my new bank account. after a few weeks, i stopped receiving cash backs for both my virgin active membership and my healthy food items. I recently (last month) received 2 sms from Vitality saying that my healthy food items refund amounted to almost R700. two weeks go by and i call. first response is that because of the billing cycle being the 27th of the month, it hadn't being paid yet. i called again after not getting paid on the 27th and get told that it was paid back on the 14th of august to which i responded that it wasn't true. i was then instructed to send a bank statement. i did and the wait continues. On friday the 13th September i get another phone call in which they realized that for "some reason" although they have my correct banking details, they are still paying them to the previous account which doesn't exist. i was promised a response by Monday 16th September and nothing happened. This is **********. they ask you to buy at specific shops and they don't pay any cashbacks. they are a bunch of ****** and i am planning on making a police case of ***** against Discovery
