Suffering due to horrible service from Vodacom Fibre support

In May I logged a call to report that my Yeahlink Voip phone is not working and since I have bought it through a Vodacom 24 month contract, it is still under warranty According to Vodacom’s clauses. Due to lockdown they could not help me during level 4, however they said they will have it replaced when lockdown moves to level 3. Its now been almost 2 months, they have just collected the phone 2 weeks ago to check it.... no feedback since. I need the landline as I work from home and use up all my airtime and even buying more. This is just another example of how terrible Vodacom’s service is!
