Airtel — 4 g tp link speed not coming for the last 2 months

Address:

160062

I have 4g tp link [protected] and prepaid [protected] mob no. For the last 2 months speed, network is not available. Data unconsumed for the period. On complaint it was told that tower upgradation job is going on, then said you get the sim reset which i did atleast 10 times. Today it was told to get the sim changed. Talked to executive and seniors regularly. No sr being raised and then told that no previous complaint in records. Same issue faced on pre-paid number [protected]. Nobody visited. Should i go for change of service provider.
