I sent an order to the customer (a mattress topper) via USPS using a label purchased through Seller Central. I am providing the package details below: Dimensions (LxWxH): 19.0 x 11.0 x 9.0 inches

Weight: 14.0 pounds

Shipping cost: $14.74 USD

The customer returned their order using the UPS return label provided by Amazon. After the return delivery, UPS adjusted the package dimensions and weight as follows: 66.0 x 16.0 x 24.0 inches

183 pounds

Due to this adjustment, $316.07 USD was deducted from my Seller Central account. However, UPS also provided a delivery confirmation photo that shows the same mattress topper weighing 14.0 pounds when it arrived at the customer.

I believe this adjustment was made in error because:

The initial package dimensions and weight sent via USPS were not altered by the carrier, so its actual weight is 14 pounds, with dimensions of 19.0 x 11.0 x 9.0 inches.

There is photographic evidence from UPS that clearly shows the mattress topper on delivery.

It is possible that the customer did not repack the item as carefully, making it slightly larger than the original dimensions, but that would not increase the weight of the item from 14 lbs to 183 lbs.

How can I dispute this adjustment?

I shipped a package USPS ground advantage.

Paid the normal charge of $4.68

Size of package 9/6/2 weighting 6 oz

USPS audited package at the same size and weight 9/6/2 6 oz

Today I get a shipping adjustment charge of $227.95

There is no way the package could cost $232.63

Talked with Amazon seller support. They told me that I need to deal with USPS .

I tried to file claim with USPS but according to them I must file a claim within 30 days. Package was mailed 5/29 but charge did not show until today 8/29

Any suggestions on my next move

Case # ID 15924783951

I recently noticed that for order ID 111-0688249-9672269, Amazon charged me $150 plus shipping costs for a returned item. This was an A-to-Z claim, but I was unable to open it as a safety claim, and the A-to-Z claim was closed. We shipped the item for only $4, so I don't understand why Amazon applied a $150 adjustment.

The item has a package weight of 0.22 kilograms, with dimensions of 7.5 x 3 x 7 inches. Given that we ship over 100 orders of this item for just $4 each, this adjustment seems unfair. I kindly request a refund for this charge and ask that it be credited to my account.

Thank you for your attention to this matter.
