Long wait in the call centre

Mweb need to employ more people in their call centre. The process is too slow. After spending 35 minutes this morning on a fruitless attempt to query my data balance, finally getting though to someone and then being transferred again and then having to listen to the endless repeats of "Just to let you know, your call will be answered", I think we deserve a faster service! Their online query facility doesn't cover all possible queries adequately.
