Venezuela, current price control regime.
Soviet Union in the 1970s
Those are two well-known examples.
Additionally, Egypt is currently experiencing a massive inflation surge. And guess what? They've been trying to enforce price controls for a few years now.

https://www.cato.org/research/troubled-currenciesNigeria is on there, you can also google articles saying they tried price controls, and inflation only got worse after they did that.
http://allafrica.com/stories/201107280822.htmlSouth Sudan also enacted price controls, after which inflation went turbo mode:
https://radiotamazuj.org/en/article/south-sudan-forms-panel-consider-price-controlshttp://www.tradingeconomics.com/south-sudan/inflation-cpiSo in all Cato's troubled currency examples (except Syria which "war zone"), inflation became much worse
after they started pushing price controls.
That's because price controls create
unrealistically low official prices for basic commodities, meaning that you can profit by hoarding then selling on the black market, which creates further shortages and causes more inflation (since it becomes a seller's market). And then the original price is
even cheaper so the profits from the hoard->black market cycle become ever increasing. It's basically a cycle that reinforces itself since the "store price" can never be adjusted based on supply and demand.

EDIT: Let me give an example with some numbers.
Say a country grows 1 million apples a year, and inflation has risen such that it's $1 an apple. But the government decides that's too high for poor people to get any apples, so they enact a price control where the legal price of an apple is 10 cents.
But the problem is now demand for apples massively increases, so the stores run out, and people start hoarding their apples, perhaps freezing them. So there are now
less of the 1 million apples actually being eaten than before. And since people were willing to pay $1 for an apple when there were 1 million to share, when there are
less to share, they're now willing to pay more that $1 on the black market, so even though no more or less apples are produced, the effective price of an apple now exceeds the original pre-control price. Add to that, that low official prices discourage producers: some apple trees are no longer viable, so supply itself drops, further driving up prices.
