PNP ASAP-The worst customer experience ever !!!!! NEVER AGAIN WILL I USE PNP ASAP

If only hello Peter allowed a minus rating PNP asap with probably score a -10. This is by far the worse customer experience I have ever experienced in my life ...so here goes this has been my experience thus far on the 11th of March I ordered a few items through the PNP asap app and noticed a few items missing and some items I was over charged for ,I immediately contacted their customer care line and escalated the query I was asked to send though pictures and stuff and was assured this will be resolved as soon as possible and after endless emails and calls I have still not received my refund , I have been passed from pillar to post and with every person I spoke to I was told it has been escalated to the refunds department and it will be paid within 10 days , yet again empty promises ...I have spent more money on airtime calling them then my actual refund itself, I am done trying to get my money back I cut my losses and move on .....below is the list of customer service staff that clearly do not help their customers ,should change their titles to customer disservice agents ...Karabo Ramoala was the first person I spoke to on the 11th of March ...I sent her a few emails and she didn't even acknowledge 1 of them, I even put my complaint on Hello Peter on the 16th of March and received a private reply that stated a manager will call me and guess what still waiting for the so called manager to call me this was over a month ago....I called their call centre again on the 29th of March and spoke to Nadine Johnson who yet again assured me my refund will be paid within 10 days , I called 5 days later and spoke to Adrian and he also assured me the refund has been escalated and he even said to me he will get them to prioritise it ....I called today and he takes my call and says this is the first time I'm speaking to him ....I asked for a manager and spoke to Randle who advised me there's an issue with there system and something to do with a migration ....yet again excuses upon excuse and guess what we the customer that supports this business suffer ....can anyone advise me off any further recourse one can take ....i strongly believe that based on principle this situation has to be escalated further ....advice to you all don't waste your money using PNP Asap ....you will surely regret it
