Appoling Upgrade experience

As a loyal customer for nearly 30 years of using Vodacom, I expected better treatment and a more professional handling of my request to upgrade. Unfortunately, my recent experiences have been nothing short of appalling. I am trying to upgrade my husbands line which is part of my contract since +/- 25 April. Since I am such an old customer my profile is still on the old system. I phoned every day from 25 to 30 April and eventually got to a lady stating she will help me. Package was upgraded BUT NO HANDSET was received. I have phoned the *** so many times that they blocked me. After calling the *** number since 03 May I eventually managed to speak to a consultant stating their was a mistake on the upgrade. Even though the quote state and being billed for a handset, the system state it was an upgrade with no handset. She then told me Thursday 09 May, she need to cancel the upgrade and do a new upgrade. My husband got text messages stating they will cancel the upgrade once the handset was received by them. According to her this process will take 2-3 working days. It is a week later and NO FEEDBACK or calls from anybody to rectify this. I am fedup and really think I shall cancel all my contracts.
