Cellc's bad service! Bloemfontein

I have had endless problems with my S5, as i booked it in approximately 6 times. I had to back up my phone so many times, no proper attention was given to the phone. Cellc gave me a new phone(S5) and had the same problems has been occuring. I spoke to the lady at the desk, the head office branch about a month ago and she said i need to make an appointment, i left my details and had no response from cellc. I called in again.. and same thing happened.. i left my details . And i got no response. Today i walked into cellc mimosa and 2nd avenue.. and they said they dont have a loan phone to give me. What was i suppose to you in the mean time? . As this outcome.. i changed my service provider too. This service is really pathetic!
