Saving my life and company

Hello Tania,

I hope this note finds you well.

You may or may not recall our case.

I will keep this short, as I can imagine you are very busy, but wanted to update you of the outcome. After you went into bat for me against the ATO in 2018, due to them issuing a garnishee over the company leaving me nowhere to go.
With your persistence we reached an agreement…saving my life and my company!

In our last conversation you asked me to let you know how we ended up and told me “show them that we would make it”!

Today I am emailing you with an enormous smile on my face…our ATO Super Guarantee Account debt was finalised in August, 2020 and today we received the attached statement from the ATO…as of 8th December, 2020 this is also finalised.
It has not been an easy journey, especially with the additional challenges of COVID…but we survived!

Thankyou Tania from the bottom of my heart, as without you I would not be sitting here typing this email.
May I wish you, your family and colleagues a very Merry Christmas and a safe New Year.

Warm Regards,

Trisha F

What a relief

Tania, I am so very grateful for all your help over the past few months. Things turned out as I had hoped, but much better than expected. My sister will also be happy because she was concerned for me.

Thank you, thank you and thanks again. I just let out a huge exhale for I was almost holding my breath.

Of course I will be pleased to recommend you to others.

Mission Impossible Achieved

Tania, You were referred to me after a relentless three year audit of my taxation affairs by the ATO. As well as threatening my means of livelihood, the audit caused enormous personal stress. But you achieved the impossible and liaised with the ATO to obtain an unbelievable result. I am so grateful to you.

As a result of your fantastic efforts I am now free to get on with my life. Thank you so much.
