Still no feedback after more than 1 month

On 20 September I wrote a review regarding feedback on my mom's smartshopper card. Pnp responded privately that it seems my mom has 2 smartshopper numbers and they're going to link the 2 cards... A week later and still it hasn't been done. My original complaint was on 19 August, more than a month ago that we're not able to view my mom's smartshopper info on her Pnp app... A query that still hasn't been fixed. I've sent so many msgs on WhatsApp, emails, FB and now Hello Peter but still its not resolved... I'm disgusted by the lack of customer services. Before Pnp handled queries quick but now, they don't even bother... What a waste of time... I wish I could rate them "0"
