Lies and the worst service delivery ever , after 10 years of being loyal with Cell C

I have 2 contracts with Cell c for more than 10 years now. One of my contract is due for an upgrade which I did upgrade 3 weeks back. The sales person said I would get my phone in 3-7 working days. Further to that she told me that the billing of the phone will be pro rated from the day I active my sim card. Its been 3 weeks now heading to the 4th week and I haven't received my device, I kept calling and was sent from pillar to post that they are running short of earphones but surely my phone would come in 2 days. Its been 5 days now and I haven't received my phone. Yesterday cell c had the nerve to sms me a bill that includes costs of this device I haven't received. When I called them I was put on hold for an hour , I kept calling the whole day with no luck. I am disappointed with the kind of service cell c has given me after 10 years of loyalty, what ****es me off more is the false hopes but when it comes to debit they done negotiate they want their money but I must wait a month for y phone be delivered. See me now see me no more with cell c I am done. Telkom here I come now I have a better reason to change providers.
