If you were affected by the Tyro outage last year in January 2021, you should by now have received an invite to join a class action. If you have not got it and think you should have it, please get in touch with me, and I will send you the details and information in the *welcome pack*.
If you have accepted the Tyro compensation offer, it does not mean that you cannot join this action. Yet, your odds of getting something are less.
You will almost certainly need to prove a legal loss to get something. That loss should be bigger than the Tyro offer of compensation to justify your entering this action. A legal loss is not the same as a business loss. I had a client whose three days of work were not considered a legal cost as he did not have to pay anything. He got transportation costs for petrol, so he got mileage and legal fees, which did cover most of his legal fees.
If you are interested in joining, you should contact the lawyers organising this case here and, if possible, your own lawyer. Also, you may want to contact Tyro directly to discuss before joining, as I am sure they are willing to discuss your specific case.
For the record, we accepted the Tyro offer, as did 90% of the people affected; we think they did their best, So we have no intention of joining this action.
PS I am not a lawyer, and this is not legal advice. I have been with them for years. We were Tyro's very first customer.
