No customer service & ****py seating area

I had a problem with my Samsung Android. I went to ask Samsung to fix it & they said only my service provider, MTN could fix it. So I stopped at the 14th Ave HQ of MTN & went to their Customer Services to get help. All relevant staff were there, but were busy. I sat & waited in a queue. After 20 to 25 mins I finally got my turn to see a lady & explained my problem. She took my phone to her colleague who was busy with Apple inventory. They chatted & she came back to tell me to go to the next building &ask for 808 service. So I walked there, stood in that queue & explained again. I signed in & sat at a really ****py waiting area (torn & dirty carpets & badly chipped glass table) & waited. People coming after me were seen before me. After an hour of being there, I got up to complain at no service. Several people were also standing & waiting at reception, annoyed also at the delay. All of us were waiting for 808. 2 ladies were at the reception: one in a red dress ran away. The other, was stoical & managed all of us. I take my hat off to her. No-one from the back was responding & she was stressed. I only got seen after 1h30mins. Really Bad service & a poorly maintained seating area.
