Terrible Service from MTN Repair Center

I brought a brand new from Hi-Online in July, the phone is working perfectly. The only issue that I've experiencing since from November was that when I was charging the phone, the indication on the phone show's that its charging but the percentage they don't increase in most cases but when i keep on trying after several time you find that the percentage does increase but when it reaches 50 - 55% it stops increasing.

Then I advised THE FOSHNINI RETAIL GROUP, and they told me to take it back to the nearest Foshnini store then I did forward the Phone Nokia 6.1 (IMEI: 35 ********** 5 02737) [Job number: M1 ********** ] to Eyethu Mall Foshnini in Orange Farm on the 23 November & the phone was collect by MTN on the 27th November to their repair center. On the week of the 17 to 23 December the guy from Foshnini at Eyethu Mall did call me to advise that the phone has been repair they are waiting for delivery then they will advise me once available.

Now it been 2 week my phone has not yet been delivered to Orange Farm, I don't understand the reason behind the delay. What a terrible service from the repair center.
