Onlineshop and refund

I ordered few items from TFG onlineshop on 27/11/2019, i paid for every thing that was advertised, TFG cancelled one off the parcels on my order on 28/12/2019, On 2nd December 2019 i was asked to log a refund for parcel they ccancelled and i did that very day.

I recieved message notifying me that my refund will be processee and paid within 3-10 days, i was furious becauase i paid them cleared funds and my money wasin their account the very day and now i had to wait for my refund and its christmas, their maximum 10 days expired around the 12/12/2019

I have been calling TFG non stop and they keep on taking me from pillar to post, until today the 27/12/2019. I guess kinhdom will have to come before i get my money back
