Kulula.com Travel Bank Credit

I had to do a cancellation of the tickets which I was supposed to use from 15 - 18/01/2020. This cancellation was done on 23 March 2020 and that is when the Travel Bank account was created. I then requested that this credit account be credit on the 14th of December 2020. It is now almost 3 months and my travel bank account has not been credited. I have made a number of follow ups as well as escalations (17 February 2021 and 05 March 2021) without any success. This is frustration considering the fact that when I requested the account to be credit, I was told that the process take 2 months for the credit to be processed but on the 14th of March 2021 it will be 3 months without my credit reflecting on the travel bank account! This is the worst service I have received when it comes to refunds! I am disappointed in kulula.com. I have even sent a escalation mail to the customer relations as well as the feedback channel and still no success!
