NOT a world class airline. So disappointed in expectation.

76 year old Johannesburg female pensioner teaching in Bangkok. Due to fly from Johannesburg to Bangkok on 6 November. Had emergency major operation on 28th October but had complications, should have been out of hospital on 30th October and possibly able to fly on 6th Nov. This is now 8 days later and am still in hospital had to change my flight. In Johannesburg made 8 calls to your local number, 8 of which took minimum of 29 minutes to answer – on 3 of those occasions YOU could not hear ME. Frustrating after 30 mins of waiting. Some time I just dropped the call myself because I saw my money flowing away. Remember, am ill in hospital. Finally I changed the flight, agreed to the price and was told had to pay via your app. MANAGE YOUR BOOKING just kept on giving me Webpage Not Available. Your guy said find better WIFI. I am in hospital unable to walk !!! Your payment URL link expired once I finally logged in to my credit card and could not complete payment. Link expired. I have just spent the past 1 hour 15 minutes trying to call you for a new payment link and after going through your ‘hoops’ your call just DROPS. I cannot afford paying for these calls and the time I have left in my life is better spent living it rather than wasting it with Singapore Airlines NOT WORKING. My booking reference is DAMIEL. I want to pay for my new ticket. Please call me on the South Africa number you have in my booking or my email. You can get my details on my booking reference. In future I will choose another airline.
