charged after cancelling

We recently cancelled our contract after only 3 months or so. Only cancelled because we had loads of issues with the services and we was really fed up. i rang up and complained that they wanted 297 quid for cancellation early they got it lowered to 99 quid. so i paid the 99 quid then a day later 297 quid was took out of our bank. My partner rang up and they said they’ll put it back in the account end of month. Awoken up this morning and another lot of 297 quid been took out. i’ve tried to ring up and get to a human to explain but no. nothing. we were first time customers and what a joke. I just want my money back as it’s so much money lost over services that were never provided.
