Poor service from Coricraft Nelspruit

On 23.11.2018 I bought 4 cushions. Coricraft Nelspruit only had 2 stock. Bonnie said she will order and inform me when I can come and collect. 2 weeks later Bonnie still did not call. I have called Bonnie 08.12.2018 saying I want my cushions. On 11.12.2018 Bonnie called that there is no cushions in stock. Now I have to drive all the way from Lydenburg to Nelspruit to return the 2 I have so that I can get a complete refund. Why sell stuff to customers if there is no stock. When will I receive my lounge set I bought 23.11.2018, is there even stock since I can't trust anything from Coricrafts staff.
