Superdrug

Yesterday 20/2 Superdrug took two payments when they should havw taken one of £37.52 (they also tookpaymrnt by mistake of £40.52 from my card). Upon notifying them. They will only 1) refund the value of the order £37.52 and put the £3.00 additional on their store “beauty card” within a week!!! (Well if i wanted to spend another £3.00 thats fine) but i dont!!! 2) send me a cheque by 9th march which is an inconvenience waiting up to 4 weeks for it to arrive, trailing to a bank then wait for it to clear. All of this because they made a mistake, is unacceptable. I have simply asked for the full amount to be put back on my card within 72 hours. They are ynwilling to do this and im furious!!!
