AliExpress complaint: Customer services are taking too long to address my issue.

I ordered a glass from Aliexpress on the 18/7/23 with a 10 day ndelivery time. It is now 16/9/23 The seller informed me that unless I paid extra postage it wouldn’t be posted as postage was more expensive (or cancel the order and they would issue a refund) because they issued a tracking number. I couldn’t cancel the order so I informed Aliexpress by opening a dispute. It is now 8 weeks later and every week I get in touch with customer services they tell me it is being dealt with or they want more information. The tracking clearly states it has not been shipped and I attached the message the seller sent me asking for more money for postage. Apparently they still need more information. I have no more to send them so I attached a lovely photo of my dog! I have asked for the procedure to file an official complaint but no response there either. It is not the money but the principal. I have been a loyal customer for many years and never had a problem but this is making me angry!
