Difficult to use Singapore Airline website

I have a lot of problem in using Singapore Airline website.

I wanted to know how many Krisflyer miles are required for a return ticket to London. The website asked me to choose Book or Redeem. So, I indicated Redeem.

I have to enter the Departing City and Destination City and the dates. Some of my entries keep disappearing. I get an error. I have to make my entries all over again. They do not remember my previous entries.

I have to try this a few times to get the entries correct. Then they ask me to sign into my Krisflyer account. I cannot remember my number. Furthermore, my points will only be credited later this month. There will be insufficient points to make any redemption.

I just wanted to know the points required. It is really difficult to use.

Two weeks ago, I called the SIA hotline. The staff checked and came back with the wrong answer. If the SIA staff can be confused, it is certainly more difficult for the customer.

I hope that SIA will consider my feedback and make their website more user friendly.
