More like an email like the following when I left negative for a drop shipper who cancelled my order and then the price jumped up + £100 and of course I mentioned the fact in my feedback
"I would like to thank you for purchasing from me and I am very sorry for the problem you faced.I have seen your feedback and I looked into the matter.
We had to cancel your item due to a technical problem and you were sent a confirmation e-mail. I have removed the item in the listing but it needs to get updated. Please do not order with us till we fix the problem.
I am sorry I couldn’t provide you an excellent service which you deserve but sometimes we cannot just stop the problems happen.
Please do not get a feeling we are not a responsible seller at this marketing.
I will be more careful next time. Please give us a second chance. Our customer’s satisfaction is our number 1 priority!! Please let me know if there is anything I can do for your pleasure."
