Extremely Dissapointed Client

Hi, I’m running a ****a shop in Marapyane and one of your bakeries ( Vaalbank), used to deliver every second day and I would order between 3 and 5 crates from them. I must say I recieved fantastic service for two of your previous drivers, namely Collen and Punch. I'm very disappointed in the service I have received from them since they have changed drivers. I have not received a delivery for almost a week now and I'm not sure why, yet they deliver to another shop in my street, whom orders far less than I do. I called the driver Tshepo, and was extremely rude towards me. I then notified the " Sales Manager" at Vaalbank ( Gilbert), who assured me that I will receive my delivery on Monday, to no avail, and I called him again on Tuesday and he said he was in a meeting and would revert back to me, which still hasn't been done. I understand I'm just a small piece of the pie, but if Blue Ribbon doesn’t want me distribute their brand, please may someone inform me, as I have had to explain to unhappy clients for the past week why I don't have a basic commodity. I'm highly disappointed in the service I have received and I have been loyal in only selling your product.
