Customer care is no longer a priority

I have been trying since Wednesday to cancel my contract with Tracker.

The number ***just rings endlessly and nobody answers.

I have now emailed *** and receive automated responses with a work item number and an attached document "cancellation of contract" which does not open.

If their customer service lines are down or faulty, why not inform the clients of this. If they are working on skeleton staff due to Covid-19, can this not be communicated?

This level of service is no longer acceptable.
