EXTREMELY BAD SERVICE

i logged a call with Miway personal insurance ale December and on 02 Jan 2018 to come and pick up my phone (Nokia 1520) that has giving me a problem over the same thing. I spoke to Leornard the team supervisor and told him they rather write off this phone and pay me since it is the the 2nd time giving me the same problem. This phone was handed in to be fixed couple of months back re a screen that is shakey apart from other problem it had. It was fixed, now its started again, Leonard tells me the problem is the battery and phone needs an upgrade and MiWay does not pay for this. This is after i called on friday 04/01/218 he said hell call back, he never did. i phoned this morning and left the message with Thabang that Leornard must return my call, he didn't, i had to phone later again and Mpho returned my call to transfer me to Leornad. My question is, why didn't they find the problem as the battery and upgrade at first...now its another story over the same problem and he insists that they cannot pay me when the phone is repairable but he did not mention this earlier. I have a problem with Miway everytime i must get service (that i pay for) i have been with them for close to 10 yrs now but their service does not seem to improve. and i recommended my sister and a friend to them (for such exremely bad service) im enough of this and my i shall seek better service elsewhere and i will leave with my recruits. SAME PROBLEM TWICE BUT DIFFERENT CAUSES TO IT THAT MIWAY DOESN'T PAY AND EXTREMELY BAD SERVICE. Is there sense in there???
