I face the same situation in 2016 , spend few thousand and expect to get few hundred CB from the so called 1st come 1st serve cash back
but end up getting 0 CB. From then on any 1st come 1st serve from HSBC I will not take part . So "fishy" and "non-transparent"..

Recently they have these Guarantee CB of RM50 for 2500 spent only I take part, and the fulfillment was delay for more than one month,
after calling the CS for 3 time and just saw the CB of rm100 in my account. Each time calling their CS will have difficulty looking for the
right CB campaign and query whether i have register via SMS for the campaign, very very unprofessional. Will avoid any such campaign
in future.

Is online topup Alipay in foreign currency..i didnt swipe during travel..i think max is rm100 for both category..
