Interrent - TERRIBLE COMPANY. Do not use!

I rented a car from this company in Glasgow in 2018. Returned the car on time. Took out full insurance before picking up the car as I know my luck. Paid for everything up front except the deposit. On return they promised full payment of my deposit of £300 within 2 weeks. Never did. Had a two year run around about the repayment of my deposit without getting anywhere. No phone number to any customer service. Phoned their booking office - no help either. Just said it was for extra insurance which is a loud of rubbish as I took the best plan before picking up the car. Wrote them a letter stating that I won't let this go. Nothing. TERRIBLE, TERRIBLE COMPANY. Hope the Covid 19 pandemic put this company into administration.
