I was concerned about returning a certain item because of expensive postage fees for large parcels, so I contacted Amazon UK customer service directly and asked whether they would reimburse the postage costs for my return. Customer service told me, more than once, that they would reimburse me all of the postage fees up to a maximum of £150. With this in mind, I purchased postage through UPS which ultimately cost £177.30, due to Amazon providing me with the incorrect weight of the item. I sent Amazon the invoices providing proof of the postage costs, and now they are refusing to honour their promise to cover £150 of postage. They will not elaborate on why, and every time I contact customer service they simply end the chat when I bring it up. I am currently missing £150 because a multi-billion pound business doesn't want to give me the £150 they promised me. After this, I will be cancelling my account and will never use Amazon again, and my friends and family have agreed they will do the same. It's shocking to me that a company as famous and as profitable as Amazon has the gall to lie and treat its customers like this.
