"swallowing difficulties"

For over a year now i have had issues with swallowing food. It gets stuck on the way down and i have chest pains assossiated with this. I was referred for multiple tests a handfull were carried out before covid hit. I was due to attend for swallow studies and pH studies to assess my swallowing reflex. I understand that there are still issues surrounding covid but i have not heard anything about a new appointment when i call i get a message saying the department is temporarily closed and to contact the referring consultant. First off 6 months is not temporary and second my consultant can not do anything with out these test results as it is my treatment is at a stand still. 

I fully appreciate we are coming out of a pandemic but surely hospital services should be back up and running especially diagnostic tests. 

Is there a time line for getting the rest of the services up and running because at this rate its noe 8 months iv been waiting i know if it wasn't for covid i would have been seen within a few weeks. 

Can someone explain when all diagnostic tests are being carried out? Whats the hold up? Is there another option i can use is there somewhere else doing the tests i can attend? 

Thank you for reading my concerns and i await your response 

Kindest regards
