Vodacom Repairs is Horrible/ ****MERS!!!!

Vodacom repair centre is horrible.One of my Samsung cellphones on contract is broken,its not working on wifi or mobile data,as i booked it in the assistant told me it might be send back with no problem found after 2 WEEKS???.Exactly as said,they done a software upgrade which was updated already,and no problem found.Immediately as i came home i test the phone and was STILL FAULTY!!!!.What must i do know as this happened before : i send a phone with another problem,which was also send back with no problem found,but as i send it back again,not knowing that my guarentee has just lapsed,NOW THERE IS PARTS NEEDED FOR REPLACEMENT WITH A RIDDICULOUS QUOTE.How can that be,very same phone with very same fault Vodacom can fix now,but at a cost opviously.What makes sense to me is 2 weeks back they had to pay for repair costs under guarentee out of their pocket ,and **** to me ,as a customer for 20 years, that phone has no problem found ,but after 2 weeks very same phone i have to pay over R2000 to get same problem fixed.

Vodacom sounds like a ****,i have 2 contracts for over 20 years by you,and now its the second time you are ****ming me to not repair a valid warranty claim on my phone,but you are more than willing to over charge me to repair it as soon as phone is out of warranty,only 2 weeks later.......Thats beyond PATHETIC.

Think i must take my money to MTN,i am sure they wont treat me like this!!!!?????
