Bad vehicle finance service

On 21 July 2017 our normal vehicle installement deducted from my account. On 24 July 2017 another installment deducted. On the the 25th I contacted the call center to inform them,the agent then informed us that it will be reversed in 7 days. After 7 days I contacted them again as no funds was reversed,the lady then informed me that the request was never complete and this will take another 7 days. Since then we have been waiting it is almost a month. This is unacceptableas I had to run insufficient unpaid items on my account of R150 per debit order. This is the worst service as they are *********** in running their call centre and delivering on a promise. Pathetic I would say.
