Invoice paid, but forgot to quote invoice number - purchase has not been accepted yet

Good morning,

On 28 January2021 I purchased an Upgrade from SDL Trados Studio 2017 Freelance Plus to the 2021 version.

When filling out the bank transfer form I forgot to enter the invoice number. Therefore I guess my bank transfer cannot be allocated to the relevant invoice. Due to this the purchase has not been accepted up and I did not receive a license up to know.

What should I do?

Many thanks and best regards,

Ute
