Expired voucher - no help no contact .no answer on the phone , no e mail response

Hi THERE

I am in a desperate need of your help and advice pleaseI had originally booked to Fly to Estonia on booking reference booking ZA***8...the flight was cancelled due to pandemic issues .A travel voucher was issued however but we still could not travel .The travel voucher number is ***

The travel voucher date was extended for another year but we still could not travel

The whole thing has become a mess and a nightmare of not knowing what and when to do anything

I have been advised by the travel agency - Travelstart -Melissa Eksteen - to reach out to you to find a solution for me because the voucher would have to be redeemed by the airline anyway so I may be able to book and fly home to Estonia to visit my ailing and aging grandfather one more time ....please please please help me to find a solution to my now expired voucher and subsequent loss of the fees I paid …

Anxiously awaiting for your favourable response
