Sad about the tarty customer service at Tymebank

I love this bank and have been using it as a second account since 2019 I have no complaints about the bank, however the customer service has been poor via email to action request. I have been trying for a few months to get my last name updated and have sent my identity document and divorce papers thought on numerous occasions. First they could not open the docs I resent then there was no response I spoke to them on the phone and sent it again twice but still no action has been taken. I had to follow up again this morning as I haven't head any feedback. Come on tymebank team please man it can't be that difficult to change a last name.
