Poor customer service and service delivery

I ordered a shower door on the 7th of December and made payment, the store/ consultants never initiated any feedback to this day, I called on the 7th of March and they confirmed that they have the stock, I went to the store on the 22nd of March and they didn’t have the door, Sipho assisted me on the 22nd and promised to have the door delivered on Saturday the 23rd, I explained to him that I am a pensioner and I am not mobile and it costs me money each time having to go into the store, it is the 26th of March and the door has still not been delivered and I haven’t heard a word from the store.
