Cell C - Fibre Internet

Good day

I have a Fibre internet with Cell C and last month moved into a new place at the same complex. ****erally next door) and requested Cell C to move my internet to the new place. Everything is installed at new place and they don't have to do any new installation. My request was captured in their system on 26th March and after many phone call and frustrations still dont have my internet moved to the new place. I have been paying for my contract since then and also buying internet on my cellphone ( which is so costly) and still no body is giving a clear steps and way forward. I am really considering to cancel my contract and get a portable wifi. I dont know how complex this small technical change is for a big company like Cell C. If they cannot manage these small queries, how they want to take more customers and give services to them.
