Bad after sales service after Nampo

On 20 May 2022 after visiting Würth South Africa's stall at Nampo, I purchased a side cutter (power plier on invoice) together with a pair of scissors from Cristopher, a friendly sales representative at the stall. Order number *** was issued. The scissors were available at the stall, but I was informed that because there was no stock on the side cutter, it would be delivered after Nampo. On 6 June 2022 I called Würth South Africa on *** to enquire about the delivery of the side cutter, which I had not yet received . I was referred to Mr. Robert Jones, who I promptly called to explain the situation. After taking my details, Mr. Jones promised to look into the issue and call back. On 15 June I received a call from Würth enquiring whether I had received the delivery, because they were following up on who had received deliveries and who had not. On 20 June I once again received a call from a Würth representative (from ***) regarding delivery of the side cutter. I was informed that the side cutter was on back order, upon which I requested that my order be cancelled and that the payment be refunded. I provided my banking details. On 4 July I called the Würth representative on ***, to enquire about the payment of the refund, which had not been done. I once again provided my banking details. On 11 July, after not having received a payment, I once again called the representative on ***. I was informed that refund payments were only done on Fridays and that my details would be sent through for payment. It is now 18 July and no payment has been made to my account. Although Würth South Africa provides excellent quality tools and friendly service was delivered at Nampo, I am afraid that the after sales service that I have experienced to date is unacceptable and is not building upon the reputation of the company.
