bad service

i had to make several calls today. They debited my account with intrest after they loaded clubcard on my account without permission. they reversed the clubcard and the intrest charged but then they debited it again with the intrest. i asked to speak to the supervisor because the gentleman on the other side does not understand the point. he rep**** the supervisor is busy in a meeting. no mention of help from their side to to get the supervisor to phone me ..... how convinient that he is in a meeting. i letf it there and i asked for an email because i would like to cancel my account. i dont trust Edcon anymore and i need everything in writing. he just kept quiet on the other side. i think that is highly unprofessional. i tried to phone back on several occations to get an email address but i was just put from on person to the other. wrong numbers were also supp****.
