Terrible service from TymeBank

I logged a ticket with them on 31.10.2019.with the problem I couldn't move money from current account to my Goalsave savings account. 2 weeks later, still haven't got resolution. Calls to call centre are waste of time, they couldn't help. Said it was a back office issue. Got a response on 11 Nov to say problem is fixed. Issue NOT fixed. Still can't move money to the savings account! This is a basic function of a bank, the transferring of money to various accounts, but seems they still can't fix the problem. I wonder if I will receive the interest I would have got on the increased balance? For a bank with no branches, you would expect the call centre would be able to fix the problem or at least, give me a progress report on what they are doing to fix the problem. So frustrating, you can't talk to anyone in authority to complain either.
