Bad Service from CCD Couriers and Rain Internet Service Provider

I've ordered a 5g package with Rain on the 15 June 2021, and there were delays in delivery from CCD Couriers because I could not produce a hard copy of my proof of address since I had to be confined indoors due to testing positive for Covid. I requested for an arrangement of doing this electronically to avoid contact of which the courier service and rain refused. Then my order was arranged to be delivered on 25 June 2021, I just received an sms from CCD saying there's a delay and they never contacted me until I contacted them and requested for delivery on Monday 28 June, they informed me they can only deliver on Tuesday 29 June of which I refused and ended up having to arrange for collection at their Fourways Offices because I was tired of the wait and have been struggling with network issues.

I arranged for transport that took me to collect the package on Monday, 28 June 2021 with the promise that my account will be activated within 24 hours.

Today is the 30th of June 2021 and the sim is still not activated. I am so disappointed at the fact that it's now 15 days since I made this order and this is not the standard promised by Rain Network, I have logged the complain online but no one contacted me, I had to call again this morning regarding this matter and was told it's been escalated to their billing department.

I am considering of going with another service provider seeing that Rain is no longer that efficient in ensuring that a customer is satisfied and treated fairly. Especially with having no one call to find out what's the matter for my order not being processed within the 3 to 5 days as their service level promise.
