Catastrophic: impossible to obtain a refund: sending of documents followed by .... NOTHING; Do not respond to follow-up emails, or respond completely off the mark. Result: reimbursement not processed for 1 and a half months, despite 2 shipments, by 2 different means.

sponsorship offer not applied either, applied after 7 months, after X reminders.

Clearly get to the point of litigation.

Catastrophic management: I have 2 contracts with them, they will clearly scare their customers away.

Modified following the answer below:
Approximately how long extended period? Because there the delay begins to have a good back. We will arrive at 2 months and refund not processed.

Does that explain the answers always beside the point ??? Why not respond by email, you prefer public requests on Google?

Has the Covid lasted since December in Lyon? (date of the sponsorship application), how do you explain 6 MONTHS late on this point?

Obviously you find the time to respond to Google reviews ...... Well before dealing with your CONTRACTUAL commitments.
It leaves to think ...
