Bad service

Order number *** I have once again received an incomplete with an error on the app that says I have received 2 canisters, I only received 1 canister instead of 3, I have paid for 3 canisters I don’t understand why I am receiving 1 and it says 2 was delivered please I need my 2 remaining canisters delivered ASAP. My last order for chairs was nothing but horror but here I am buying again. This is totally unacceptable
