AMSTEL AND AMSTEL RADLER - OUT OF STOCK IN GAUTENG SINCE DEC 2018???

Having been a loyal Amstel beer drinker for the past 40 years, I have been seriously let down by Amstel for the second time in my life. I have also got to enjoy the light Amstel Radler but have had NO STOCK in any bottle stores in Gauteng since December 2018. The first let down was when Amstel went off the South African market a few years ago and I was left "high and dry" for about seven months when SAB stopped producing Amstel. When it started production again in SA, I was still a loyal and avid Amstel fan drinking my favourite brew on a regular daily basis. Now in January 2019, amstel NRB dumpies and Amstel Radler were out of stock at all bottle stores. Amstel Radler is still out of stock. Makro SA has not had stock since Dec 2018. WHAT IS THE PROBLEM???
