Poor service

I purchased a pair of shoes on pop clothing online and after querying the color both in store and on their customer service number I was assured I was going to be sent the correct color.... after paying the additional R60 delivery fee I was sent the wrong color shoe. I logged a complaint and requested a manager to collect the correct color from the warehouse and deliver it to me before the long weekend.... they refused and instead have logged a return. so now I wait an additional 3-5 business days for something the store did incorrectly not me as a customer. I have requested to have my shoe delivered asap as well as my R60 delivery fee reimbursed and I've been told it cannot be done. having checked how woolworths would've handled this I was told the manager would've sourced the shoe and deliver it to me in person! apart from the lady I'm dealing with in customer service being helpful I'm very disappointed with the service from pnp after I told them there was a problem with their shoes labels and being assured I would receive the correct item.
