PLEASE DON'T USE CELL C EVER

I ordered 2 contracts via their specials, the Sales agent captured my address incorrectly, please note this persons job is to capture customer's data and to understand how South African addresses are written (basic knowledge). I then received a text message to mention the phones will be delivered between 8 and 5 and that I must be available at the given address, after waiting an entire day I had to call to find out what was going on, the agent told me it could not be delivered due to an incorrect address, I mean it didn't even end with the word street or road, how could it be a valid address? Then I correct the error I call again today only to need to correct it again and after 1 hour the sales agent who originally assisted me calls to tell me the address is incorrect - are you kidding me??? Then I call their management who only wasted my time even more, DID ABSOLUTELY NOTHING to remedy the situation and just told me my phones would only be delivered on Monday which is UNACCEPTABLE!!!! If I can cancel these contracts and send back the phones I swear I will, this is the WORST CUSTOMER SERVICE EXPERIENCE IN MY LIFE - WORST COMPANY WHO SELECTIVELY MAKE SURE THEIR EMPLOYEES IQ ARE AROUND 20. NEVER EVER AGAIN IN MY LIFE.
