New phone not charging

I took an iPhone on contract on the 26th of April, on 13 May I realised it wasn't charging, so on the 16th Of May I took it back to telkom pavilion, I waited for more than 20 minutes before I could be assisted then I was told they need to take the phone for repairs and unfortunately they can't give me a new phone and they do not have loan phones. My first installment of R900 was deducted on the 15th and the following day I had to buy a new temporal phone. I only received an SMS today (20th) saying my phone has been sent for repairs and I might have to pay for the repairs. I am very dissappointed with Telkom. I expected a better service
