Pathetic service

We attempted to order a tv online and once we attempted to purchase the item disappeared off the website. Apon calling customer service, which was unhelpful, they advised that it was no longer available. The next day the tv was available online again, and we attempted to purchase and was successful. Later we received a notification to say that the order was cancelled. When we had called customer service, they advised that the item is no longer in stock and there was nothing they could do about it. Not only did this inconvenience continue for 3 weeks with unresolved queries but also I no longer qualify for 2 discount codes. Items are in stock in store but not available online. Not once has pick n pay offered an alternative or a resolution, I am stuck in frustration with the customer service. There are plenty logged calls and 'attemped' escalations. Obviously the customer must figure things out for themselves.
