Customer has opened a dispute with no evidence and my funds have already been taken from my account

[MoW]

Hi there,
A customer has made a transaction and picked up the goods on the 15ht of February and on the 11th of March the same customer has opened up a dispute saying she does not recognise the charge and asking money back. I have just checked my current daily balance and I have noticed that the amount on dispute has already been taken off from my net profit from today, this is  completely unacceptable as Square is basically attributing to me the issue the customer is facing (with no evidence the customer is legitimate in the claim) while I have instead done the correct thing and delivered the goods to the customer.
This situation has already created enough distress to a business that has been hardly hit by a pandemic, Square should not penalise businesses before the investigation is completed and especially when I have provided Square with evidence I have not only fulfilled the order but also tried to contact the customer to resolve this,
