Ruined holiday!!!unwanted upgrade

Absa has been my bank for years and I have been very happy. The day before my overseas holiday a few weeks ago I called them to inform them I would be travelling overseas so the could expect activity in other countries. on my silver absa credit card. I also told them when I would be returning . During my holiday I was sent an sms informing me that my card had been upgraded (at no request from me and without my permission )and told me id ne getting a new (unreqested card . They then cancelled the card I was using in Australia so I could no long access my cash !!!!!!! They knew I was away my card was only expiring next year and was a valid card . Shame on you ABSA you ruined my holiday and I am still not able to use my card when I called they said new card will only arrive in 5 days in SA helps when your not there.
