Unhappy Client

I bought a cell phone (Mobicel Ultra) at Pep Cell Pan Africa Mall Alexandra November 2018. , I woke up one morning and my phone could not switch on so I took in to get repaired on the 29th November 2018 at the branch of purchase. the cashier who assisted me (Mpho) gave me a receipt (repair id ********** ********** ) and advised me to come in 6 weeks time to collect my phone. I then returned to pep cell on the 22nd January 2019 Mpho told me that the phone was not collected by repairs as yet, so she will book it again. She did not give me a receipt this time, she only advised me to return to the store in a month's time. 26th February 2019 I went back to the store to collect my phone, and to my surprise I was informed that the people in repairs did not come to collect my phone at the store AGAIN, I did not understand this so I asked for the manager. She came and advised that its not their fault that repairs did not come and collect my phone. The manager asked for a receipt and I told her that Mpho did not give me a receipt the last time. she then printed a receipt with the Repair id ********** 387649H. The receipt was dated 26/02/2019 but this was cancelled with a pen and written 22/01/22. I told them I need a phone ASAP and they told me to come back tomorrow. I returned today February 27th 2019 and the 2 ladies decided to give me my phone back in the same condition I gave them 3 months back. I am an unhappy client. The 2 ladies were rude does not have customer service at all, they showed no remorse. Its been 3 months I have 2 repair Id no's but my phone is still not fixed. I need answers.
