The stone age of online ordering

My wife placed an online order on 4th September 2019. On 9th September we received an sms notifying us that the order was ready for collection at Mall of Africa. I went that evening to collect at customer services. The lady that assisted, informed us that the parcel was not there and that the sms that generated must have come from head office. She said that we should wait for a second sms from the branch to indicate that the parcel had arrived before we bother to come through. It is now the 11th of September and no additional message has been received. Firstly, it is ridiculous that we have to wait for a second message, as I wasted both my time and petrol in making the trip to collect (which is not even advised when a purchase is made). Secondly, what type of service is this that I must wait over a week to pick up clothes that I have already paid for, when delivery was stated to be 4 days. We are extremely dissatisfied with the service that we have received using online purchasing for the first time with Edgars. Considering a chain store such as yourselves must compete with other online businesses for sales, the poor service we have received is actually unacceptable. I would much rather purchase from another store that I can trust to adhere to their delivery times and correctly notify me of when to collect. If someone wants to get their order in time for a special occasion, don't bother ordering from Edgars.
