Extremely dissatisfied due to false representations that were made

I previously stated that I canceled the tracking device in on of my vehicles in October 2020 and paid a cancellation fee. My account was debited until February 2021 irrespective of the cancellation. Eventually the service was cancelled on the 8th of February 2021 and I was advised that the debit orders that were not meant to be debited will be refunded in 3 weeks. The 3 week period has lapsed and I have still not been refunded. Basically it has taken 5 months for the funds to be returned.
