Cell c disappointing service

In March 2018, my cell phone needed to be repaired. I requested a qoute from cell c Greenacres which I received and deposited the amount on the 13th March. A month later I received a phone call stating that cell c were unable to allocate money they received from me. I complained about the length of time it took for someone to contact me. After which I received an sms stating there was no despatch date recorded. I returned to the store to be told they had been involved in a ******* and were closed. I had to visit another store to be told that my phone is with the courier.I visited greenacres cell c again and was told my phone was returned not repaired date not recorded. After explaining to an employee at cell c i was informed that service centre head office had slipped up. Today 1st June I went into cell c Greenacres again and was shown my unrepaired mobile which leads me to think that my phone was never sent for repairs. I am not impressed at all with the service I have received. I need my phone urgently as I use it for work purposes. I demanded I get a new phone still awaiting a reply.This has been a very tiring and disappointing experience . I had no choice but to send this letter. Please I need help and my phone!!
