Virgin active sales scheme

I am extremely disappointed with the poor administration of Virgin active. I joined them on 3rd of January 2020 to qualify for the promotion(that was sold to me) of getting the first two months free thus my first payment should have been for the 1st of March. They have deducted for January and February and I tried to contact Virgin numerous times and whenever I spoke to a sales lady and ask her name after explaining the entire situation she cut the line. The salesman at Virgin active where I joined tried to be very helpful but it's out of his hands I've never been so disappointed with the poor results. The debit order went through twice and now I have a bad credit record due to unresolved matters from their side.
