I am so unhappy, dissatisfied, frustrated with my OPP A15 phone, in just 3 months its going off and on, uncontrollably. I took it to Vodacom SA (Cresta Mall branch) They claim they have replaced it but I am getting the same problem. Useless technicians, company and service, both Vodacom and OPPO are playing a very dangerous game of fooling their customers. User's recommendation: Contracting companies and manufacturers must be liable for putting sub- standard products to customers.
