Telkom Mobile's Error

Telkom has now moved over from roaming with MTN to roaming with the Vodacom network. Sad to say that I have had telkom mobile for a rather long time with no complaints but when your network provider decides to change their roaming partner, I would think that its only fair to inform your clients before doing so. I have moved from having exceptional signal to having no signal. I have made numerous calls to the telkom call centres only to find out that the calls are being escalated with no feedback or resolution. 3 weeks gone by and I am still awaiting feedback. Rather poor service from Telkom Mobile. Not impressed at all!
