Mobicred seems to have the perfect business model (they never close your account and keep on billing you).

I settled my mobicred account on the 20th May. I then sent Mobicred an email on the 21st to request immediate closure of my account Ref: wf_***. On the 1st, Mobicred took off R100 debit order despite this. I made Mobicred aware of this, requesting a refund as well as the closure of my account. We're coming up on another month-end and I can see they'll charge me another service fee for having the account open. Heck of a strategy, they never close your account and keep on charging you a service fee. I would recommend steering clear of them.
