Paid surcharge for a heavy item but I had to lift it myself

I’m extremely disappointed with my delivery experience through Superbalist. I was charged a R299 surcharge for a “heavy item” on the basis that the delivery driver would require an additional person to assist with lifting. However, when the delivery arrived, the driver was alone, and I had to physically assist him myself in lifting and moving the item. This completely defeats the purpose of the surcharge. If I am expected to lift the item myself, then there is no justification for charging me extra for additional labour that was never provided. I essentially paid more money to do the work myself, which is unacceptable. I would not have agreed to or paid this surcharge had I known that no additional help would be provided. This feels misleading and unfair, especially considering that customers pay delivery fees specifically to avoid situations like this. I expect this matter to be taken seriously and for the R299 surcharge to be refunded, as the service paid for was not delivered. I also urge Superbalist to review how these surcharges are app**** and communicated, as this experience has significantly affected my confidence in ordering large furniture items through your platform again.
