OMG, your TA asks you 55GBP in order to convert your flight to a voucher where BA does it for free. That is strange.
Regardless, the best way to learn about your flight status is to go to MMB on BA.com, add your contact details ( e-mail / phone number ) over there and they would e-mail you automatically when your flight is canceled or changed. Even though you gave your e-mail and phone number to your TA, it might not be inserted in BA's own system so I would check if BA has your contact details registered on your booking.
