Non-delivery headaches

Ever since I have made payment for Rain 4G internet subscription, I am slowly regretting the decision. My first struggle was when I couldn't pay for the said subscription because of issues with their app failing to communicate with my banking app to facilitate the payment. Only going through the following day (last Saturday, 3am)

Now, I am sitting with a non-delivery issue. For two consecutive days starting yesterday I have received an sms, from the courier, promising delivery on the day. The creepy part is that both the sms's came through at exactly the same time 9:30am, after which is deafening silence. The similarity in times makes me wonder if perhaps the sms are from an automated system!!!

Trying to find support in Rain's supposed Facebook support page or Twitter is pointless because they either block you or blue tick you and move right along. What I hope for infact is a clear plan of delivery, not this thing they are doing now via their couriers of informing of a delivery that never occurs. I suspect they might respond to this post with other 'grand' assurances but I really don't need their cosmetic response what I need is an honest delivery plan.

If they can only deliver next week, let them say so and then keep to that agreed date. In any case they can't go any further in dragging down their reputation in as far as I am concerned. I sincerely hope when I eventually receive the sim it would be worth all this trouble.
