Poor service

Poor service I received today at parkstation and the customer centre for intercity,online when you google intercity there is a number that appears,this morning I tried numerously to reschedule my ticket on time,but the number did not go through and later when I arrived the bus had left I showed cashiers proof of my calls which they requested after I did that,I was told that the number I had been calling it's a *****sters numbers and I'm asking them as a customer how am I supposed to know that because it's the only number I saw on intercity Xpress,they could not assist me and the consultant was rude and unhelpful I honestly didn't like the service I received from Portia today.i hope she get a written warning and I hope to get my bus ticket rescheduled
