Got this email from SC

"For the month of May 2020, we inadvertently credited an additional 0.40% bonus interest on top of the actual 1.5% bonus interest on your credit card spend. As a gesture of goodwill, we will not be reversing the additional bonus interest credited. We apologise for this error and have taken measures to avoid reoccurrence."

Same here. Only base rate

Normally base and save bonus interest credit on first day of the month. Then spend next day
