Account Frozen for what

So I have been a client for over 5 years.<br> <br> Ive never skipped a payment but my account is frozen.<br> <br> I bought a Garmin device online and had to return it because of issues with Discovery. Took it back to the store and when I wanted to check the credit that i could still buy for it said R0.00. I got concerned that they haven't credited my account and I phoned the call center. They stated that my account has been refunded but my account has been frozen. He could give me a reason why but all I have to do is take my ID to the closest Duesouth and get them to verify something.<br> <br> I arrived in the store and nobody knew what I was talking about. The gentleman in the shop was on the phone for over 15min with nobody being able to assist him.<br> <br> I would kindly request if my account isnt fixed before the end of the week you can close it. Its not that I need an account from Foshini Group I just like the 6 months interest free option.
