Terrible customer service

I am trying to purchase a replacement power adapter for a Russell Hobbs appliance. I am located in Jhb but have not been able to get any response from the Jhb phone number. I eventually managed to get hold of someone at the Cape Town office of Home of Living Brands who told me that the product is in stock but in order to get a quote I would need to contact them on their WhatsApp number. I tried that 4 times in the space of about 24 hours (across two business days) but got no reply. I then decided to drive to their head office in Fourways. A very friendly lady in the sales office assisted me by creating a service request proforma invoice for me. However, they do not take payments on site and the only way of providing the proof of payment is to send it on the WhatsApp number. I was given a number I could phone in the event that I did not get a response. Now I have sent the proof of payment on the WhatsApp number 3 times, had no response and there is no answer on the number I was given. SHOCKING SERVICE
