MTN is disappointing a loyal 6 year customer!!!

After numerous amounts of times contacting the branch where i purchased x2 honor 200 lite phones, discussing numerous issues regarding both phones which they confirmed is not normal, i am still awaiting feedback and its been 6-8 months. I have contacted Sarel at Honor who is the area manager as i understand and still NO SUCCESS, i will be delivering both phones on Saturday and i demand for a full refund of everything that i have paid up to now for the phones. MTN is quick to ask for money which never happens as i ALWAYS pay on time but sorting out issues, they are pathetic!!! I am sick and tired of fighting and begging for service!!
