Worst terrible customer service at rain store greenpoint Cape Town

They don’t even deserve the 1 star. Received the worst terrible customer service at Rain store Greenpoint in Cape Town. Yesterday I signed up for a rain month to month wifi. The sales person was very friendly and helpful, he advised that I could collect the router in store today once payment is done. I made payment and sent POP. Today after 10am during my work tea break. I was attended to by a tall dark guy, I don’t know his name. He took my id and searched and said payment was not allocated so he can’t help me, me being so confused I asked him how is that possible when I payed and sent POP. He started explaining to me like I was a 2 year old, raised his voice while his 2 female colleagues looked at me like I’m crazy. I asked the what else can they do as I took time to drive there and might not find time again and need this router as I’m out of data. With the worst attitude the started blaming the sales person as this had nothing to do with the, and that they have system issues. No apology for any inconvenience, nothing, and I left the store. The sales person called me and apologised for any inconvenience caused and told me that he pushed for allocation of payment I can now go back to the store and collect. I go back to the store again during my lunchtime, I get there I find the guy who assisted me earlier on busy with another customer, so one of the ladies who was there in the morning assisted with a terrible attitude on her face. I gave her my id, and proof of adress, so while she was capturing my information the guy finished with his customer and opened his phone to show the lady that was assisting me perfumes that his friend sold, so while I’m waiting for assistance they had a full blown conversation about perfumes that are being sold somewhere, and she clearly couldn’t multitask cz she stopped everything and paid attention to this guy and they got excited over these perfumes while I’m waiting there to be assisted. I asked them if I should wait for their conversation before I could be assisted. She gave me a terrible attitude and told me that I don’t have to be rude. Me being shocked I asked her how I’m being rude when they are wasting my time. She said “you can clearly see that there’s system errors here”. The guy asked where I am working, I asked him what does that have to do with anything, they both laughed and the guy left. She then told me that u won’t have connection today anyway as there’s still system issues. I asked for her manager, she gave me a runaround and couldn’t give me a contact person.
