Poor connectivity, no turn around time and sense of urgency - dissapointing

Everyday after 6PM i have poor connection for the last couple of months and i have reached out to Rain to alert them about this issue, they have connected me to the technician Erin who request that i reboot the 5G however even after actioning his instructions the connectivity stays poor, its always on 2.4G. He has requested i do a speed test and i give him the results he then says he will escalate it to the senior technicians. Last week Tuesday a lady called me to check if im home and i advised that she can call me on Wednesday when im home as i will be closer to the router not only is the connectivity poor after 6 PM now its through out the whole day and i advised her of the problem she also requested i do a speed test and i gave the results she then said she will log a call for the Technician to come to my area and have a look however i will be contacted that didnt happen until this day. As soon as she put the phone down my connectivity was poor again, i reached out to rain again and i was told they will log an emergency ticket for the connectivity until to date im still struggling with connectivity always going onto the device to get assistance but im not getting any joy yet Rain is 1st to debit from my account yet their service is pathetic. They even went as far as asking for my name, address and e-mail address couldnt they pull that from their system unless they were improving someone's connectivity instead of mine since they didnt even know my address
