Pathetic service

Took a contract on a S 20 FE in Dec had a issue with the battery. Returned it within seven days. I was replaced with another phone. Upgraded another contract to the Samsung S20FE. On The 7th day started experiencing the same problem called the sales person they advised to bring the phone the next day in as it was too late. Took the phone on the 8th day in sale person I dealt with was not in. Was advised to take it directly to Samsung in Nandi drive and it will be sorted much faster. On the 10 th day Monday I took the phone to Samsung was advised it takes 4 to 6 weeks with them. It will be faster with cell c. Went back to cellc gateway and booked the phone in 25/01/21. Now apparently it's over the seven day period so they have to fix the phone. Spk to sales agent several tyms. Was advised yesterday phone is gonna be repaired. What nonsense I had to run around so much. A brand new phone battery is faulty and u are repairing it. And I'm still without a phone. Pathetic customer service. Samsung S20 fe has a factory fault for sure. 2 phones the same issue. This matter should be handled asap. As I am tired of waiting for my phone.
