*********** pick n pay store manager

We bought a hisense tv from pick n pay Greenstone and after a year the tv stopped working it just went off because it was still under warranty we went to report the matter at the store and one of the employee took our receipt made a copy and told us to leave the matter will be reported and a technician will contact us a week passed with no communication we went back to the store only to find out that the employee who took the receipt never reported the problem instead he put the receipt under the table ok now the process has to be started again ,we waited a technician finally came and told us that the broken part had to be ordered and it takes 5 days to come so we had to wait no problem 3 days later we get an sms that says the tv had been fixed so we called hisense that said they can't find the part so it will give a credit note to the store we should go there they will tell us the next step we got to the store they told us we will be refunded our money back but we told them that the same tv is now more expensive so we want a fixed tv or exchange as promised by warranty so the store manager bongani told us he will escalate the matter and call us the next day to tell us the outcome days passed and we went back and bongani told us he was busy with stock taking he doesn't have time for us after an exchange of not so nice words he then checked and said hisense found the part and some1 will come it's been a month with no tv and back and forth with hisense and pick n pay still no solution very disappointed with the level of incompetency of both the store and hisense call centre .im guessing I might need to buy a tv since they can't fix it
