PnP ASAP

I purchased products that has a weight attached to it on the app. The app charges the maximum amount and then adjusts the pricing according to the actual weight of the products. PnP ASAP however did not do this. My invoice was for an amount double what it should be. I phoned the support centre and spoke to Roxy. Roxy indicated that they will pick up the products within the hour and exchange it for the correct weights. Its 3 days later and I am still waiting for them to pick up perishables. I have also sent an email from the app informing them that the products were not collected. They just don't reply. There are other companies with similar options as PnP ASAP which I will much rather use going forward. I will not buy from PnP ASAP again as they take your money and then go quiet!!!! Bad bad customer service.
