That can happen...
If the return is delayed, you should just contact the Support report.

In almost all cases, a solution can be found without difficulty. The most important thing is not to simply ignore the return, as Isa is often part of a company programme and additional costs can arise from prolonged delays.

There is often also the option to extend the usage phase or continue using Isa at a discounted employee rate. Support will be happy to help you with this.
