Hi

I am from the UK and have been in Canada for the last two years and used TurboTax for my return last year. This year however I am back in the Uk to activate my second visa but due to a medical emergency I am currently unable to return to Canada. Which means I cannot access my Canadian phone number which means I cannot access original Turbo tax account so had to create a new one, without my Canadian phone number I cannot access my CRA account to change an address which means I cannot file my taxes. I have tried to use the full service but cannot get passed the current mailing address page because I currently do not have a mailing address in Canada. What on earth am I supposed to do!? I would love to just have a call with someone to go through the whole situation but cannot find a way to with my UK number
