RCS card activations - lack of ANY customer service.

Activating a lost PNP store card has turned into a nightmare. I have a store account with RCS that uses a smart shopper card. I had lost the card and went into the store to replace it. Got the new card and pick n pay call centre did the switch. Then it was up to RCS. I was at the store on the phone the first time for more than 30 minutes. They then said all was sorted. I went home got my pin reset and was told i was sorted. Went back to pnp and it didnt work. I went home and called only to be told it wasnt activated (another 15 minute call) and that i needed to go back into store with my ID to activate because of all the *****. So i went back to the shop again. Stood like an idiot on the phone for over 2 hours trying to get this resolved. This was the satuday. I spoke to 2 managers who eventually told me to go try somewhere else to add insult to injury. They did nothing about it. I sent a complaint on the Sunday and still havent received any response. I went back to a different pnp and tried again there where they couldnt get the merchant number so they couldnt help me. I had to go to another pnp in another area where i stood for another 2 hours trying to get this resolved. To be told they will investigate and get back to me. This is exactly a week later and i still havent heard a word. When i try and call im getting no joy. Honestly the worst service ive ever received in my life!
