Service failure

Re : Service Delivery I have been trying to change my debit order to the 30 of every month from the 28 May 2019. I donot work as i have been unemployed and I will not have any funds in my account. I however i managed to get a job. It only pays commision on the 28 so i want to move the debit order to the 30June 2019. I called your call centre and they said they cant changed it. I told them im unemployed and will get funds from my relative to assist me. I was put on hold and the phone dropped on me. I tried calling the call centre again last week and wasted my airtime as my calls just get dropped. Please sort out this matter urgently as i don't have money in my account on the 20th and I will incur cost for returned debit order. I will be expecting the changers to be done.As i never missed a payment as I was always happy with the service and provided.

I have also emailed the complaints department but nobody has come back to me.
