Sterns - Disappointing Service !!!

I was rather disappointed by the service I received from Sterns East Rand Mall regarding an Online Order I placed for a name pendant. I placed the order online on 22 September 2021, and selected the option to “pay in store with account”. On arrival at the store on 26 September 2021, they had no record of my order. No order was on the system and I was advised that they would have to upload my order on Monday morning. Once loaded Sterns would contact me with a reference number and update. I was further disappointed to hear that I could not pay on my account as only cash deposits are accepted – Sterns website clearly states you my pay on account. But what has really upset me, is that I was told this pendant would take 4 – 6 weeks !!!!!!! What ???????? As per Sterns website delivery can take up to 14 working days once the order has been confirmed. Surely as large franchise store like Sterns, should have standard operating procedures in place to ensure that what is advertised on your website in fact is happening in your stores???
