Review Capetown Claremont service center cheating!!!!

I drived BMW more then 10 years and I really like but there was horrible exprince this time...

I had really the worst experience in Capetown Claremont service center.
My vehicle had 100,000km service and maintence plan and I brought it just before 100,000km to Claremont service center.
One of service staff told me that he will check everything which must be done within ********km.
Especially he commented that he will change engine oil and filter and break pad and etc
because it is comming service within 1000km.
Service was delayed about one week which had never happend before.
After one week he didn't print out what they done which must be signed all the time.
and he told me that they changed engine oil and all the filter and etc.
I belived and came back ....

After service I drived less then 1000km and I saw that I must change engine oil again.
and I complained to the service department staff that he didn't change engine oil.
He ignored me and just is telling that he didn't told me about it and he can not help at that time.

BMW don't care with customer if vehicle service plan is expired?
They delayed and didn't print invoice and explain and cheat with me ...
