Shocking customer service rochdale branch

We hired 8 adult suits and 2 childrens suits from greenwoods, all the suits were great apart from my eldest sons pants. He was measured and when he went back for fitting they were 8 inches too long for him! They were sent back to be corrected and arrived back instore 3 days before the wedding, they were still too long for him and so were taken up instore and collected an hour later. On the day of wedding the hem had fallen down before he even walked up the aisle! He was so uncomfortable and constantly pulling them up all day it spoilt our day and looked awful on the photographs. I complained to headoffice who have basically said it was not there fault, so in effect blamed my 8 year old son! When i took the complaint further to the manager of 1860, he basically said the same and it was out of there control! This is truly shocking customer service and needless to say I will be taking this further. Would never use greenwoods again as there customer service is absoloutely disgusting.
