Nomore Auto & General

I had a policy with Auto & General, lately i was involved in an accident when phoning Auto & General no respond. I ended up fixing my car & sold it. I notified them in advance to cansel the policy with them, & they have agreed. But surprisingly month end they have deducted the premium. On the 1st of December I phoned them to refund me they said yes they will. But it take 2 to 3 working days. I phoned again after 2 days. They said maybe on friday the 4th or monday. Nothing happened. On monday i phoned & the lady responded by saying refund was done but i didnt receive that money. Now she said i should submit my bank statement to prove. Why should i submit my bank statement if they know they didnt refund me. Is only R650 ... For the refund of R650 they send me from pillar to post knowing they didnt refud me, and they failed to give me proof of payment.And i want to tell auto & general and to all the people of south africa the worst experience i had with Auto & General not to be in the same situation.
