Unable to modify the mobile phone number (the mobile phone number was abandoned a few years ago, but the customer service tried to use the old mobile phone number), resulting in the inability to withdraw funds

The mobile phone number verification is required to withdraw funds, because the mobile phone number was abandoned a few years ago, so I want to change the mobile phone number, but the customer service is mentally retarded, and clearly said that the previously registered mobile phone number has been abandoned, and it needs to be changed to the current mobile phone number, but They desperately called the old phone number to verify. It's no use holding a photo of your ID card. Anyway, it is stupid to call the previous mobile phone number to verify. As a result, it has not been possible to withdraw money. In addition, the platform has huge spreads, about 40 pips in gold. horrible.
