POSTAGE LABELS

Just got a big shock when I looked at my charges and found them to be excessive.   On checking, I have four charges for ordering postage ebay postage labels.    In actual fact, I didn't print any of these - I was just checking how to do it and then decided I would stick with my click and send satchels that I have a stock off even though they are more expensive (I also got charged the fee for these as well !!!)   Now, having trouble finding any info on how to cancel - or how to actually contact e-bay (which I would prefer to do)   Is there any one out there who can help ?   MARLENE
