Vodafone Missed Gift Card Promise

Vodafone I installed a 6-month package on the 551-*****02 phone you carry with you. During the installation, it was written that a 150 TL gift certificate would be given. But the gift certificate did not arrive. Installation of customer service. They said the problem would be resolved within 48 hours. It's not resolved. Customer transactions are repeated. This time they said the problem would be solved within 4 days. Still not resolved. Customer transactions are repeated. This time they said the problem would be solved within 1 week. Still not resolved. The customer representatives I spoke to were Merve and Yunus Emre. The strange thing is that the last customer representative I spoke to said that no record had been created regarding your complaint before! We are back to square one, still no solution. It's been 20 days since the upload. What kind of company policy is this? He deceived the customer who refused to give him a gift while selling, then kept his promise. Does it suit a company like Vodafone for 150 TL? I will add the screen recordings as pictures. For 150 TL, re-evaluate whether you prefer this operator without having to experience uneasiness and victimization like me. When you experience any problem, no solution is produced, only distraction is provided.
