Worst experience

Bought a five burner gas stove by makro capegate less than a year ago. When using the oven it trips the electricity now recently only. So I mail customer service and I send through all documents and I was requested to send pictures on WhatsApp too. Which I did. Days later no feedback! Yesterday I send another email asking for an update and no feedback or response. Product is less than a year old. Paid for the technicians to come out and install the gas and connect the stove. Paid delivery but now that there is a problem I’m the one who Must ask so whats happening or what is going to be done about it.
