Salea Agenta dropping calls - Unbelievable

I called today twice to downgrade my current product and add a new product to new property. Both times my calls were dropped off by the agents because they couldn’t locate my new address. During my first call I thought my minutes was deplete, but it happened again with the second call, different agent. Im still shocked,never have I experienced this, a call centre agent hanging up on a customer?? Mweb service is the worst. Im actually not adding a new product anymore, im placing a notice of cancellation on my current product . I’ve already had a bad experience with Mweb a month ago and for this kind of treatment to happen again??? Im done with Mweb. Im even shocked to see how many other customer are complaining the same behaviour i.e calls being dropped off by agents yet its still happening. Im done.
