Poor communication and service

My first wedding ring arrived and was too big and poorly made. Wooden inner ring broke on the first day. Ring was sent back and a new design chosen. Am happy with the quality of the new ring but not with the service received. Empty promise after empty promise around delivery time frame, lack of communication all around. I had to collect the ring from the airport myself as Kallie had safety concerns, it was sent to OR Tambo and not Lanseria as I requested. To date I have not received the valuation certificate I was promised on the 22nd of December, and Kallie is ignoring all emails, calls and WhatsApps.
