Apollo Pharmacy — Non stop promotional messages

I purchased a product via the Apollo pharmacy website. Since then, I am receiving multiple promotional SMS and communications per day.

I don't want to receive any of these as they are very bothering. My number is also registered with DND.

I tried to block contacts, unsubscribe to SMS (APOLLO UNSUB to [protected]) but nothing works, I am still receiving those promotional messages.

Their customer care number is unreachable as well.

Please resolve quickly as I receive around 10 messages everyday.
