VERY DISSATISFIED with the management of my request for reimbursement of lessons given at lunchtime
1. the room where the lessons are given closes on December 20, 2018 (which I was not informed about when I registered in October): first disappointment!
2.I am invited to use my tickets before December 20: being convalescent it is impossible for me
3.I must provide a medical certificate to justify my reimbursement request while other registrants in perfect health do not have to provide proof ...
4. I am finally told a refund in mid January: having received nothing to date, I am relaunching
5. I receive a response telling me that the processing is complex (a bank transfer in 2019 is complex?) And that therefore I will be reimbursed ... MID MARCH ???
It is absolutely ABNORMAL that the refund period is so long - if I make a purchase on the internet and the item does not fit I return it and get my refund promptly!
