Poor Service from online

On the 10th of March, I purchased a product online for collection at Wonderboom store. On the 19th I received an SMS , stating my order was ready for collection. I went to the store to collect and I was surprised to be told that the item was delivered in Germiston store. I never selected collection in Germiston. The consultant at the store told me that he will sort it out and he will have the item delivered to me at no cost. That promise was not fulfiled. I returned to the store two (2 April 2019) weeks later to inquire and I was told the same story. I was told the issue will be rectified and I will get feedback at 12 noon. The time came and pass with no response. If its not bad website (slow response and poor layout) its bad service. I don't understand why I was not given the same product in the store because its available on the shelf. I wasted my time and petrol visiting the store twice to collect the item.
