Airlink problems time and time again

"I had 2 return tickets booked from Richards Bay to JNB last year during CoVid Lockdown. I could not get a refund and therefore I wanted to book a new ticket with my credit from JNB to RCB and bak (19 - 22 March 2021). I got in contact with Cindy Ndlovu regarding this matter.

She advised me that there would be a penalty of about R880 which I was willing to pay. I emailed her to proceed with the booking - to which I never received a reply.

Upon calling yesterday to make the booking, I was informed that your airline is no longer flying to RCB. I am highly disappointed in the service I received from your company, yet again."

I have emailed the above to the customer complaint email address and received only a generic automated reply. At my whits end with this company. 10/10 would not recommend.
