Bad customer service

I am utterly appalled with the bad service I have been receiving from rain over the past 3 weeks. Rain was supposed to send me a 101pro replacement router they delivered the incorrect router small tiny router in the morning of Friday 7 March 2025. I called to advise that the incorrect router was delivered to please deliver collect this incorrect router and deliver the correct router. After numerous call attempts to rain they committed to delivering between 2-5pm on Friday 7 March 2025. Which did not happen even though I called twice @16:30 & 16:50 advising that my parcel had not been delivered even though 5pm was fast approaching. I was assured that delivery will happened and also at the same time agents were also dismissive. I have since called rain 3 times yesterday looking for a solution all I get is escalation which go no where. No follow ups no call backs they all end the same going no where and ending at the same point of frustration. Rain does not respect or value their customers specifically long standing customers such as myself. Their service has drastically declined and there is no attempt at resolving important queries specifically where the error is on they part.
