Rubber Sealant - do not order online

I ordered paint online on 26 February 2026 and paid for the paint from Rubber Sealant. Since then I tried to contact Rubber Sealant 5 times on two cellphone numbers that appear on the invoice. They did not answer their phones nor did they return my call. I then sent the invoice to their Paarl branch and Gauteng via whatsapp and request a delivery date. Nobody came back to me. I sent an email today to request the same, but needless to say - nobody came back to me. It is absolutely shocking. I never had such bad service from any company ever in my life - and I am a pensioner.
