"Query sent we will call you" no help from cell c !!!!

Hello. So on the 22nd of May cell c called me and asked if i wanted to upgrade as i was almost due for it. I told them sure they told me about the hauwei p30lite wich sounded good so i told them ill choose that one in pea**** blue amd the gave extra data on it. They said it would take about 2-3 weeks to be deliverd and i recieved it on the 15th of june. I saw on the phones box it was not the color i reqeusted and i only opened the box to look at the phone wich was the wrong color and also had i very prodtruding camera. I called them the next day to ask them about the collor they said they dont have pea**** blue in stock and it would take 4 months to ship it in. I asked them to come and recollect the phone wich is unused and reverse that upgrade so i can choose a samsung phone. They collected it on friday the 19th of june and said i should call after 3 bussnes days. I did so and they only told me my query was recieved and they will call me wich they have said about 10 times i tried to get in contact with them throughout this whole proces and not ooce did they call me back. So the 3rd of july i recieved an sms saying that the upgrade has been reversed i tried to call them no answer. I then went online and requested a call me back on intrest in the a30s wich they called back about in like 5 minutes. I then said i wamt the a30s and told them about my previous upgrade wich was said was reversed and they then told me AGAIN my query has been sent and they will call me..... all i want to do since my upgrade was reversed is upgrade to the samsung. How hard can that be. All cellc agents are useless and just sais query has been fowarder we wil call you then never call back. I request some call me imediatly as today i recieved an sms saying my service wil be suspended as i have not paid bit how can you expect me to pay when the hauwei has been sent back and reversed!! I just want to upgrade to the samsung !! I even visited in store where they were of no use "cause i upgraded online and will have to continue online through the call centre" wich sucks by the way... i just want 1 person to call me so i can deal with the same 1 person till my query os resolved cause i have recieved like 10 different reverance numbers cuase no one calls back. Theyr quick to call and sms when they want payment but has absolutely no customer service. How have they kept theyr bussines running this long??... please i require assistance asap!! Someone from cellc please call me that can actualy help and not just send a query ive got too many damn queries sent...

Thank you
