Bad service

On 16 September 2017' I filled in a request to change my banking details for my debits due to fact that my old account is no longer in use. This was well in advance for the debit to raise correctly. They have failed to lodge the debits and caused unpaid charges on my old account of R175 x 2 for the last two months. This is unacceptable!!! Now my account is unpaid at virgin Active and my bank harges almost equal the membership fee!! Someone has not done their job, and it's not my problem. Virgin active must fix this!!
