All cylinders ordered and delivered through the MzansiGas service will always have a plastic seal around the valve of the cylinder. This seal is your guarantee that the cylinder has passed a final check in our filling process and is the correct weight and in a safe working condition.
Mzansigas does not refund stock that was correctly invoiced and delivered. Should a cylinder have been ordered and subsequently discovered to be the wrong size Mzansigas will exchange the cylinders for the correct size as long as the original cylinder still has it's plastic seal around the valve in tact. The delivery charge for the exchange will be for the customers account.
Please feel free to contact us personally in regards to your individual situation should you wish to discuss refunds or exchanges in more detail
