Pathetic Customer service

I have recently taken out a product with RCS , the application and process wo aquire the product was fantastic, easy quick , and pain free.

However to find out or get help there after is **********. I recieved an SMS stating for December my debit order will come off the 15th , tomorrow, I have been trying to phone in since recieveing hte sms (11/12/2017) I select option 3 Customer care , as option 1 is sales , option 2 is follow up on application. I have been phoning in from opening hours 8am every day and hte moment i select option 3 I am put in queue saying "experiencing extremely high call volumes" from 30 seconds after opening hours ????? I sit on hold for more than 30 minutes at a time where I then need to hang up as I do have obligations to attend to like normal peiople , I try to phone through out the day and the same mess. RCS wont refund the time I sit on hold which by now as ammount to over 4 hours of talk time, and noone in other departments are willing to assist just saying " only customer care can help" I find it pathetic that no matter when you phone new sales and follow ups are answered in under 30 seconds flat, yet for assistance there after after NOTHING F""ALL.
