No Refund after 6months

I am so appauled by the poor service received by citiliner and by being a regular customer I dont like to complain however I am so frustrated about the service received and dont know what else to do . I booked 2x tickets to Ladysmith in March 2020 for April and due to the covid we obviously could not go on this trip. I phoned and requested a refund they said it would take 30 days ,still nothing was done I had to resend everything again. My edgars account could not be credited so my banking details was requested which was also sent. To date nothing has been done and I have received no communication. It is now 6months and I find this very poor customer service especially in this difficult times. Please can someone just get back to me and asisst as I feel that I do deserve this. I am a pensioner and I do expect a refund.
