Bad service . I am a pensioner. When I went on pension I paid Edgars morewith the aim of setting the account. I didn't buy except for contact lenses from the optician wrath R800 in May 2018. My instalment kept going up items of the payments I made. When i asked for brake down I was sent account of balance of R1200.00 but instalment due was R70 when I query that was told to pay R80 x 3. I paid x 2. When I went to pay the sat t lement amount of R610 as per the email account they sent me,they said it is now R690. Wanted to cancel cellphone insurance was sent to another counter to do that before I pay. Coming back the settleMent amount was now . R100 I paid that and asked d to close the account was told thathat they don't close the account the same day you paid, must come back the next day to close the account. I am a pallet by the inefficiency an lack of proffetionalism in handling my account they failed to resolve my account problem in spite of me trying to get it sorted out for since May. The sat lement amount that changed three times on the same day and refusal to close the account after I paid the sat lement amount.
