Disgusting service from Vodacom

Have been battling to cancel 3 contracts that have expired more than 2 years ago for the last 7 months. First call was made 02/06/2020. Contracts not cancelled to date. Have started withholding payment on those 3 contracts as my instructions are not being fulfilled. I called again this morning with reference number and AGAIN was told that they will escalate. 8 months of battling to get this done and they just wipe their ****s off. Now my phone has been suspended after I told them that I lodged a complaint with the communications ombudsman and that my calls to them are now being recorded for use as evidence. Never in my life come across something like this. Have been with Vodacom close to 20 years and their service has never been this low and disgustingly ***********. Now awaiting a supervisor to call back on request. Jah right! like that's gonna happen. You should be ashamed of yourself as a business.
