Makro never delivers orders

On 29 November 25, I placed an online order for a basic box of Huletts Equisweet Sugar. On the same day, it was handed to the Courier Wumdrop. On Monday 1 December I received an email that the delivery Failed because they phoned the recipient but there was no answer. WHAT A LAME EXCUSE. I told them and gave them instructions to deliver at the address they have. There is nothing to confirm. The delivery address is EXACTLY the address they have to deliver to. I requested on numerous occasions for the parcel to be delivered. Wumdrop then confirmed that Makro refused to give them the package. On Thursday 4 December Wumdrop confirmed that they waited 4HOURS at Makro for the package but the failed to give them the parcel. Yesterday 8 December Makro calls me again and confirms that my parcel will now be delivered today. Its 16:30 and still no delivery was made. I have requested x3 times to refund my order + delivery fee. But then they call me and promises a delivery. I WANT MY REFUND ASAP. I WILL NOT WAIT A DAY LONGER FOR EITHER THE PACKAGE OR THE REFUND. What you are doing to customers is unprofessional and *********. I will never support Makro or use Wumdrop ever again
