Poor Customer Service - PEP Online

I purchased a cell phone online ( Stylo Apex 5G). This phone, in particular was advertised with an MTN promotion namely "20gigs free - 10 gigs day and 10 gigs night. Apart from the amazing offer price of the phone (R1599.00), it was a really good deal with this promo.I purchased the phone online on the 26 June 2025. I went to collect the phone at PEP Maynard Mall, Wynberg. I asked the Cashier to help install the SIM card and to activate the MTN 20 gig promo. She frowned for a moment, then checked, and double-checked on the system but no promo reflected. She advised that I contact MTN. I sent an email to MTN customer care and they could not find the promo on their system either. I went back to PEP and told them that MTN cannot pick up the promo on their system either. At this point, I was highly frustrated. Then, I went to the PEP Facebook page and notified them of my unhappy experience. I shared all the required documents they requested to hopefully find the Promo that was advertised online with the phone that I bought. I have been in communication with them for more than a month and yet no resolution. They have simply just stopped communicating with me. Let's hope that they will reply when they see this review.
