Marshmallow recently changed their payment system and have changed my debit order date from the 27th of the month to the 17th, without asking me if that date was suitable. When I asked them to change it back to the original date, they told me that I would need pay two amounts in one month in order to do that, even though I didn't ask for the change of date. I started making enquiries on the 20th May and to date, I am still waiting for Jeff from "The Marshmallow Team" to "review my complaint" Apparently he needs almost two months to do this. Absolutely disgusting customer service!!
