Not receiving what you paid for & Poor service

Bought a 300W solar panel from Proton Solor. As normal one would assume a 300w solar panel would be 24v. Only after being connected to my solar system did I realize it is in fact a 12v solar panel, tested and confirmed with by a electrician. With no specific data on the website relating to the items where stock is being ordered from which in my opinion is done intentionally so Proton can send you whatever item they feel like without having to stick to specs . Probably should have realised when the panel arrived with battery clamps instead of the normal MC4 connectors. I sent a mail enquiring it to which I never received any feedback. To resolve the issue I proceeded to purchase another solar panel assuming I would receive the same panel which could have been connected in parallel with the other panel to up the voltage to 24v which would have worked on my system when i received the 2nd panel I received a 24v panel. I again sent a mail to which the Business manager/ Sales (Christa Masia) rep**** stating that the first solar panel should have been 24v which as mentioned before was tested by a certified electrician as being a 12v panel. I was advised to send through images to a whatsapp number she provided which I have done. With once again no further communication or feedback regarding this issue. I will give it another business day and if I do not get any feedback on what Proton is going to do to resolve the issue I will take it up with the consumer commission.
