HI Mohamed,
In this case can you raise a support case over the global numbers so someone can assist you - https://support.microsoft.com/en-us/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2
Please keep the docs and identity ready that you own the tenant and domain so the Data Protection team can validate it.
Hope this helps.
