Linked personal bank account deposit via in-app

So, tried £10 this morning as a test and it went straight through, so then did some more and yet again it has left my bank but not hit my FT account!!

Thought maybe because it was an issue with the free account so opened a stocks and shares ISA at a monthly fee and tried to transfer some money in and yet again it hasn’t hit my FT account!

This is ridiculous I now have £1600 floating around somewhere and no one from FT is getting back to me!
