Big Basket - Deficiency of Services Negligence irresponsibility and false promises

Big Basket disappointed me extremely with its negligent and irresponsible grocery delivery service. So far this year I faced many issues like late deliveries (BB Now deliveries) and inefficient Level-* customer support (both call and chat support). Apart from these issues, I was also dissatisfied with one order placed on September *, ****, since the M.R.P. was not mentioned on one particular product. My most recent order placed on Big Basket on September **, ****, was just another example where I had to experience a clear Deficiency of Services. Here are the details :

It was a scheduled prepaid order. One of the products which I had ordered was missing. The item's name is Glow & Handsome Instant Fairness Cream for men (** grams). The order was modified in advance and even though I got the refund to my BB wallet, it seems unfair. Why was I able to place the item in my shopping cart before checkout in the first place?? Why isn't Big Basket updating or refreshing the stock of the items on a real-time basis?? This is clear negligence by the company and a waste of time for me. I will not accept this irresponsibility since I feel this causes extreme frustration for any customer.

I am just confirming a few details. First of all, I already raised a grievance on the National Consumer Helpline portal related to the Deficiency of Services against Big Basket on September *, **** (Major Issue: M.R.P. missing on one product). I confirm that as a response to my first grievance, on September **, ****, I received a call from the NCH team of Big Basket. I lifted the call and an escalation specialist (Sunitha) spoke with me. During that long conversation, I clearly remember that Sunitha assured me that she would definitely try to monitor my future Big Basket orders in order to avoid any problems. But since I had again faced an issue related to my order placed on September **, **** (Non-delivery of one product), I feel like the response and explanation given to me by Sunitha for my first grievance on the NCH portal was a False Promise.
So, after September **, I again filed a grievance on the NCH portal on September **, ****. In that grievance, all I demanded was a small compensation along with a detailed apology from an escalation specialist of Big Basket's customer satisfaction team. So, as a response to the latest grievance, on October *, ****, I received a call from the Big Basket NCH team once again, and this time another escalation specialist (Wasim) had two long conversations with me. He just gave me a detailed apology and the best possible resolution that he offered was that he could get the original undelivered product delivered to me without any delivery charges. (Glow & Handsome Instant Fairness Cream for men (** grams)). But, I did not accept this since I no longer needed that particular product on October *, ****. Instead, I just asked Wasim if he could waive off the delivery charges for my next Big Basket order (irrespective of the order value) as a token of apology. But, he declined that request and so, I feel this is unfair. After multiple issues with multiple grocery orders over the past few months, I feel Big Basket brand has to show more courtesy and provide me with a small compensation.
