TERRIBLE CUSTOMER SERVICE

I have never experienced such terrible customer service in my life. I have been expecting a refund from APM Bus since the 26 of April 2018. till today there is nothing. All i get is excuses when I call their call centre. 1st it was vouchers that we were being forced to take, which I refused because it was not my fault that the bus was not available due to strikes, I sent my bank details for a refund 3 weeks ago, which they promised to pay but nothing. I HAVE HAD ENOUGH OF THIS SERVICE!!! CAN WE GET OUR REFUNDS BACK AS PROMISED! I would not even dare to recommend this bus company to anyone.
