Bad Service

On the 6th of April 2019 I took my phone to cell c carlton centre for it to be booked for a repair since the screen was cracked. Last year I had a replacement phone since my phone got ******.So when I went to the store I had two cellphone boxes as I was not sure which one has the new IMEI number. When I was filling in the form I asked the consultant to tell me which IMEI number was correct between the two. She then provided me with an IMEI to write down for the claim. Three days passed with no communication from C Surance which is when I decided to call them and they told me that the IMEI number I had written down was the old one and not the one for my replacement phone. So I went back to the store to rectify this matter and was told that the phone was already received by the repairs with the incorrect IMEI number .I myself had to call C surance to find out what to do as the consultants seemed lost ,I was told that the store had to contact the repairs and it took them forever to call them because they were busy with gossip. When the consultant finally came back she told me that the repairs department is closed and she will call them on Monday. Today I was the one who had to call and remind her to make the phone call and then I was told that the repairs department is on strike and theres nothings she can do.The most frustrating part is that I have to go back and forth now and its costing me time and money. I am really not pleased with any of this ,now my phone will take even longer to get back as it has to be rebooked and no one from Cell C seems to be taking my matter seriously.
