No follow through despite promises to do so

On 5th Ovtober 2022, Dean from the escalations department phoned me to establish the reason for my ongoing problems experienced with data connectivity since taking out my data contract with Vodacom on 10 Sept 2022. He advised that he would sent the issue through in order to check the network coverage in the area within which i live. Following that he informed me that they would then investigate my settings. He promised to follow this through and to keep me in the loop. Needless to say, i have not heard a thing from him! A lady phoned me on monday to confirm the issue and i told her what was discussed with Dean regarding network coverage etc. I have not heard from her either although she promised to get back to me. Vodacom, you are well aware of the fact that i have had ongoing problems since inception and yet your actions reflect that you do not care about service delivery!!! Get this problem sorted out!! I said that i wanted to cancel my contract due to this non existant service and or availability, but nobody responds to that either!!!
