Pathetic service

After Cell C contacted me to upgrade my contract, i contacted Cell C Zevenwacht Mall (possibly the worst cell C in Cape Town). i requested the Samsung S21+ which i was told to collect today. when i got there, the salesman wasnt in but Evanja Davids assisted. She gave me just the normal S21 because they sold the S21+. She also said that if i dont like the phone for whichever reason, i can return within 7days. i got to the office and didnt like the phone and called them to request an exchange, spoke to Mikyle who said i can bring in the phone and they will cancel the upgrade immediately. When i got to the store, i was refused the cancellation by a suddenly very rude Evanja. I then contacted the Customer Care line and spoke to Nompumelelo who said I can return within 7 days. I contact Cell C Zevenwacht with this info and they now need to to contact their head office. Head Office now says its a second hand phone and they blank refuse the exchange. as with everyone else, i cant wait to cancel the contract with Cell C.
