Customer service nightmare

Wow. Had to move from upstairs to done stairs beginning of the year and had to pay a cancellation for 2 month's. Now my landlord needs to move back in and I requested a transfer to her name. They say do it on the portal. You do it on the portal and they confirm there was an issue. You try redo it on the portal but now the portal isn't opening. You request that they do it manually because they said it needs to be done on the 1st which is tomorrow and now they not answering your emails about the issue on the portal and OTPs not coming through either. They better transfer over because their portal is a mess
