Bad excuses

Placed order on Monday 30 March. Told person that took order that I had 3 empty Kegs to return. Received delivery Wednesday 1 April. Driver told my staff they can not take empties back because there is no space on truck - not my problem - I worked my payment out with those empties included. Send rep SMS asking what **** this is - not having space on the truck - but as usual no response from him. Phoned call centre just after 8 on Thursday. A lady got back to me - did not take her name - should reflect on system I hope. I told her I was going to place this on hellopeter. She asked me not do it as she will try to sort it out. at 9H50 on Thursday ( 2 April ) morning she phoned back and told me that the empties will be picked up that same day and requested my e-mail address as they would send me the ct note via email. When I got to my business this afternoon ( Monday 6 April ) I noticed that it was not picked up at all. Who gives the driver authority to deny pick-up of empties?? Another thing - why do they decide to put my rating of service delivery as excellent on my invoice without asking ??? So now I will not be able to order stock because of my outstanding payment I suppose ...
