Complaint

I have been a loyal customer for more than 20 years. Doing my last upgrade I did not receive what I asked for. After many follow ups and queries, no one was able to assist, and had different stories. Asking them to go listen to each recording also did not happen. In the end I they have to collect my upgrade, I have to cancel the whole deal afterwards and then have to go into a branch to do another upgrade. The upgrade that I originally asked for is no longer available. SO NOW WHAT?? I am being inconvenienced because they did not deliver and is not helpful. I have been battling with this now for two weeks. Maybe the time has come to move to another supplier
