Bad liposuction or slow recovery? 3 months later and I have excess fat on my back. (photos)

What do you expect when you used a clinic and not a private practice boarded PS? From the before photos and your ht & wt I believe 3 liters would have been the amounts I could have removed. You stated ONY 1 liters and appears no attention to detail of liposuction techniques. Where you under general anesthesia or awake? Best to seek only in person second opinions for revision lipo. Guys the saying, "the cheap way becomes the expensive way!" applies... 

Thank
you very much for your question and photographs. At three months’ post-op, it
is still too early to assess the full benefits of your liposuction procedure.
It will take up to six months for residual swelling to resolve and the tissues
fully heal. However, if you have any further questions or concerns, I recommend
speaking with your operating surgeon.

With that many areas being done, I would expect a longer healing period and not base my opinion on the amount of fat removed. Lipo is not for weight reduction and, often, even small amounts from under the skin will give a dramatic result. Be patient and reevaluate after six months.
