I am not happy at all

I am not happy at all with their services. We booked accommodation with them last year November for December we then postponed for this year Easter then Covid happened I sent them a refund request in March after they announced the lockdown. Level 1 was announced and I tried calling their office the was no answer, last week Thursday they called me to say they need proof of payment told them I no longer have it it was an ATM deposit and the slip was lost. Called on Friday the lady I spoke to said they will be doing refunds on Friday to this day nothing was paid, Called again on Tues 03/11 spoke to another lady she said they dnt know when the payments will be made I must wait for them to call me. Like really how unprofessional they are it's almost a year but it's hard for them to refund a mere 1400 I am so disappointed shem
